I Become A God, Exposed By A Reborn

"It's arithmetic progression. 99

Xia Qingqing closed his eyes and pondered, arranged the numbers in his mind one by one, and finally came to the result, "The invigilator's regularity of opening the door every time is calculated according to the arithmetic sequence, so it is not random at all. The room number of the door is regular.33

Arithmetic sequence refers to a sequence in which the difference between each term and its previous term is equal to the same constant starting from the second term.

Arithmetic series?

Zhuan Gao Hua knew what he meant, he was not illiterate after all, but he thought about it for a while, and said in a puzzled way, "No, if it is an arithmetic sequence, the invigilator has opened almost all the doors of the room in the past ten minutes.

Xia Qingqiu saw that Zhuan Gao Hua hadn't reacted, nor did he show Bao's contempt.

Instead, she explained soberly analytically:

"The invigilator opens the door every thirty seconds, and within these ten times, the number on the door opened by the invigilator is an arithmetic sequence. 31

"Ten times to open the door, it means that five minutes have passed. At this time, after five minutes have passed, the security layer will be changed once.

"After the security layer is rotated, the invigilator will change a group of room door numbers to open the doors regularly."

"I was in the test room on the second floor just now, and the invigilator's first room door number was opened ten times, and the sub-police was one—"

"Number one, number ten, number one, number nineteen, number sixteen, number nineteen, number seven, number seven, number nineteen, number thirteen.

When Xia Qing said his apology, Zhuan Gaohua finally reacted, "One, four, seven, ten, thirteen, sixteen, nineteen.

"That's right, the invigilator opened the door for the first ten times by randomly selecting from this set of numbers."

Xia Qingyu calmly said:

"And the rotation of the security layer, the invigilator will also be rotated."

At that time, "when you went to the examination room on the second floor, because of the rotation of the security floor, the room number opened by the invigilator of the examination room on the second floor was already from 2, 5, 8, 11, 14, 17, 2 The set of ten numbers is starting to be randomly chosen."

"So it is." Zhuan Gaohua finally figured it out, "Then the security layer is now rotated, we are now back in the second floor examination room, did the invigilator change another set of numbers to open the door randomly.

"It should be. Now go back and have a look. By the way, ask Sister Ding what the number of the room the invigilator opened the door before, so that you can be sure."

Zhuan Gao Hua's heart was agitated, he was about to pass the assessment, but he suddenly thought of something, scratched his head, and said in confusion, "Miss Xia, even if we know that the number of the room where the invigilator opens the door is regular and random, But it doesn't seem to have anything to do with the test answer, right? 9)

After all, Director Liu, the tour teacher, has already said that their clearance condition is to find the right door.

"First go down and confirm my conjecture, if it is true, then the so-called correct door, I also have the answer in my heart.

"OK!"

Hearing this, Yuan Gao Hua's heart was agitated, and he suppressed his excitement.

It is better to make Gao Hua go downstairs first. After coming down, after confirming safety, he continued to shout.

Soon, Xia Qingshoe also came to the examination room on the second floor. When they got down, neither she nor Zhuan Gao Hua moved first, but waited for the invigilator to open the door.

Zhuan Gao Hua was nervous and excited, according to Xia Qingboot's guess just now.

Then the invigilator of the second floor examination room will also change a set of numbers after the rotation of the security layer, and then randomly open the door in this set of numbers.

And this set of numbers is zero, three, six, nine, twelve, fifteen, eighteen, twenty-one.

zacha one by one

The door opened.

This time, earning Gao Hua's rare, there is no panic in his heart, but a look of anticipation.

number twelve!

Not far from him.

Zhuan Gaohua looked at the numbers in front of the room, he clenched his fists, his face flushed, and he looked very excited.

After taking a deep breath, he said solemnly, "Miss Xia, it seems that your reasoning is correct.

Xia Qingshoe also had a look of joy, and taking advantage of the thirty-second gap in opening the door, the two quickly came to Ding Xiaoqiao and asked.

After learning that they went to the examination room on the third floor, the number of doors opened ten times was one by one.

Number two, number two, number eight, number seventeen, number twenty, number twenty, number two, number seventeen, number eleven, number eleven.

After ten times, five minutes passed, and the security layer was rotated, but because five minutes had not passed, the invigilator only opened the door four times.

The order of opening the door four times is No. 6, No. 12, No. 0, No. 12.

Hearing this, Xia Qingboot held the handrail of the corridor and showed a relaxed smile, "It seems that I am right."

"Miss Xia, which door do you think is the right one. 17

At this time, Yuan Gao Hua had a deep admiration for the little girl in front of him, but he also knew that the time was short and it was not the time to chat, so he asked straight to the point.

After all, Xia Qingqing just said that as long as the verification is correct, she can know the correct door.

Ding Xiaoqiao next to her was stunned. She felt that her IQ couldn't keep up, but she could still hear her words clearly.

Xia Qingboot, this little sister, has found the right door, so fast?

You must know that her brain is still like a paste now.

Xia Qingboot didn't respond, but started to read the numbers:

"One, four, seven, ten, thirteen, sixteen, nineteen, these are seven numbers."

Two, five, eight, eleven, fourteen, seventeen, twenty, these are seven numbers.

"Zero, three, six, nine, twelve, fifteen, eighteen, twenty-one. These are eight numbers. 93

After Xia Qingyu arranged all the numbers in an arithmetic sequence, Gao Hua and Ding Xiaoqiao suddenly woke up after they made it clear.

"The right door, inside the third set of eight numbers.

Without waiting for the two to speak, Xia Qingboot continued to talk, also sorting out the analysis in his mind:

"But the sources of pollution are the derivation of the rules, they have no thinking consciousness, everything acts according to the rules, and the behavior is dead.

"So, it's impossible for us to try the right door from one room to the next. That way, we can exclude consecutive numbers and test the right door from the numbers zero and twenty-one."

"""According to the real society, generally speaking, whether it is an apartment, a community, a staff dormitory or a teacher's dormitory, there is no room like zero."

"So, my inference is that number zero is the right room.

After Xia Qingqing finished speaking, Zhuan Gaohua and Ding Xiaoqiao had a very tacit understanding, and gave a thumbs up to the little girl who was twenty years younger than them.

This time, it made Xia Qing boots a little embarrassed.

But suddenly Ding Xiaoqiao said, "No, if it's room zero, there are five rooms zero. After all, we have a five-floor examination room. 39

Hearing this, Xia Qingshoe didn't speak, she looked at Zhuan Gaohua.

Seeing this, Zhuan Gao Hua was a little puzzled, his heart sank, and he thought about it, "It's really not right. 99

Obviously, not only Ding Xiaoqiao's pig brain was overloaded, but Du Gaohua was also infected. In other words, earning Gao Hua can't use his brain now, otherwise he should be able to figure it out.

Seeing this, Xia Qingqiu said helplessly, "Room 0 or 21 on the security floor is the correct room.

This time, Xia Qing boots said clearly (Zhao's) clearly and clearly, and this time the two of them came to a complete understanding.

The security layer rotates every five minutes. According to Director Liu, the inspector, the security layer is absolutely safe.

They thought that the security layer was a place for students to rest and think, but they did not expect that the real room door was hidden in the security layer.

"Then what are you waiting for, go to the security layer now.

However, Xia Qingqing stopped the two and said bluntly, "The security floor is now in the exam room on the fifth floor, which is too far away. My suggestion is to wait for the security floor to rotate upstairs, or we will talk downstairs."

Hearing this, Ying Gao Hua and Ding Xiaoqiao nodded subconsciously, thinking it was very reasonable.

The two of them obviously didn't realize that what they said to Xia Qingqing at this moment already had the meaning of obedience.

In the back of Xia Qingboot's mind, Chen Che's consciousness was checked.

As he said, the source of pollution this time was a test for Xia Qinglin, so he remained silent and did not say a word.

But even so, after reading it all, he couldn't help but admire Xia Qingqiu's IQ.

Xia Xia Wei really gave birth to a good daughter,
