Find the pattern to fill in the numbers, what to fill in the last 3 numbers? - Answer.

Analysis: 23-15 = 8, 31-23 = 8, the following number is 8 larger than the previous number.

Gradual.

Pinyin: xún xù jiàn jìn

[Explanation]: It refers to the gradual deepening or improvement of study and work according to certain steps.

The Analects of the Constitution"Don't complain about the sky, don't care about people, go to school and go up, who knows me?" ”Zhu XiNote: "This is self-proclaiming, self-cultivation, step by step. ”

[Example sentence]: She usually writes from one angle, not from several angles; It's just writing gradually, not intersectingly. ★Mao DunHow to evaluate the Song of Youth ?

Pinyin**: xxjj

synonyms]: Step by step, from shallow to deep

Antonyms]: One step to the sky

[Lantern riddle]: snail; Walk in line

[Usage]: as an object, a definite; For study or work

[Story]: Once upon a time, Ji Chang went to worship the archery master Feiwei as a teacher to learn archery, Feiwei asked him to practice the basic skills of his eyes, he went home to watch his wife weave, and practiced to open his eyes without blinking at all. Feiwei asked him to practice seeing small things as big things, and Ji Chang put the small in his hairLiceSeeing it as a wheel, Feiwei taught him archery, and since then he has become a sharpshooter with every shot.

The last three are 39, 47, and 55, which is a series of equal differences, with a difference of 8, and the previous plus 8 is the value of the latter one.

Fill in 39 47 55

So this is an increasing series, and the tolerance is 8, so 31+8 39

47+8＝55，

15 and 23 are separated by 8, and 23 and 31 are also separated by 8.

Summary. Hello, glad to answer for you. According to the title, 36, 25, (16), (9), 4, 1

Find the pattern and fill in the numbers 36,25,()4,1

Hello, glad to answer for you. According to the title, 36, 25, (16), (9), 4, 1

The law is 6 2, 5 2, 4 2, 3 2, 2 2, 1 2

What to fill in the next number, find the pattern. Fill in.

Reason: This sequence is called: Fipuccina sequence, which can be expressed by a recursive formula: a1=, a(n+2)=a(n+1)+a(n).

That is, the items starting from item 3 are the sum of the previous two items of this item.

Summary. Looking at the first five numbers, we can see that the 1st number plus 3 gives the 2nd number:

3 + 3 = 6 Add 9 to the 2nd number to get the 3rd number: 6 + 9 = 15 Add 3 to the 3rd number to get the 4th number: 15 + 3 = 18 The 4th number plus 9 to get the 5th number:

18 + 9 = 27 Under this law, we can continue to reason: the 5th number plus 3 gives the 6th number: 27 + 3 = 30 The 6th number plus 9 gives the 7th number:

30 + 9 = 39 So, the complete sequence is 3, 6, 15, 18, 27, 30, 39.

Find the pattern and fill in the number +3,4,13,16,()32

According to the given sequence +3,4,13,16,()32, let's fill in the blank with the pattern of the kernel chain. Looking at the first four numbers, Sun talks about it and finds that the difference between the first and third numbers is 9, and the difference between the second and fourth numbers is 12. The difference between these two values is 3, and the number filled in is also plus 3.

So you can guess that the 5th number ying should be 16 + 3 = 19.

Looking at the five numbers of the previous Nian eggplant, we can see: The 1st number plus 3 gets the 2nd number: 3 + 3 = 6 The 2nd number plus 9 gets the 3rd number:

6 + 9 = 15 The 3rd number plus 3 gives the 4th number: 15 + 3 = 18 The 4th number plus 9 gives the 5th number: 18 + 9 = 27 Under this law, we can continue to reason:

Add 3 to the 5th number to get the 6th number: 27 + 3 = 30 The 6th number to add 9 to the high game to get the 7th number: 30 + 9 = 39 So, the complete sequence is 3, 6, 15, 18, 27, 30, 39.

Hello, is there a problem with this question 83 If it is 283, there will be a pattern.

The following number is 3 times the previous number + 1

1, 5, 2, 6, 3, 7, (4), early (8), 5, 9, (6), (10). This problem is not so complicated, and the next number is connected, which is this law. As a question in the first grade of primary school, let the child start with the simple, do not calculate addition and subtraction, just let him count.

Look at the bold words, and then look at the ones that are not bold, and you will see the pattern.

Unravel roll: 3+1=4 i.e. 2 2

7+1=8 i.e. 2 3

31+1=32 i.e. 2 5

127 + 1 = 128 i.e. 2 7

Power: 2, 3, 5, 7 are not composite numbers (the common factor is only 1 and itself), and the next one is 11

Crime: 2 11-1=2047

is 2 n+1, and the previous number 2 plus 1 is the last number.

2,3,4,9,10,11,30,31,32 Find a regular number.

Regularity: Subtract 5 each time

Each one is 3 times the previous one plus 1,283,850 and then decrementing by 6, so the result is that you can fill in 65.

Analysis: Observing the number series given, we know that from the second term, each term is obtained by adding 3 to the power of n-2 (n is the number of terms) of its predecessor Zhifan, and the answer is derived from this Because, Ji Mengdan 3=2+30, 6=3+31, 15=6+32, therefore, 15+33=15+27=42, so the answer is: 42 Comments:

The key to solving this problem is to observe the given sequence of numbers and arrive at the law that each term is the power of n-2 (n is the number of terms) of its previous term plus 3.

Summary. Find the pattern to fill in the number, (23

Is there an analysis, teacher.

Wait a minute, I'm driving a train, please forgive me.

You calculate according to this rule, if you don't understand anything, you can consult me!
