Fill in 1, 1 in 8, 1 in 27, 1 in 125, 3 in 4, 1 in 3, 16 in 9

1. 1 in 8, 1 in 27, [1 in 64], 1 in 125, [1 in 216]
They are 1 1 / 2 1 / 3 1 / 4 1 / 5 1 / 6 cubes
3 / 4, 1 / 3, 4 / 9, 27 / 64, 81 / 256
They are 3 / 4 to the - 1 power, 0 power, 1 power, 2 power

Fill in 2.3.4.9.8.27 ()

Sixty-four
8.27（）

1 / 3, 2 / 4, 3 / 6, 4 / 9, 5 / 13, ()

Answer: 6 / 18
Molecular: 1 23 4 5 (6)
Denominator: 346 913 (18) the difference between the two numbers is 1 23345

Look for the law 1, 2, 4, 4, 7, 6, 10, 8, (13) just want to know what the law is?

Look at this group of numbers separately
Odd digit: 1 4710 13
The last number in this sequence is three times larger than the previous one
Even digit: 2468 810
The last digit of the sequence is two times larger than the previous one
I hope it will help you and have a good study

Four year primary school test questions: find rules and fill in the blanks: 1, 6, 4, 8, 7, 10 (), () 13, 14

10 and 12
This problem is easy to do without a part of the score, first remove 6, 8, 10, (), 14, and then leave 1, 4, 7, () 13, there is 1 + 3 = 4 4 + 3 = 7 7 7 + 3 = 10 10 + 3 = 13, so the first one is 10
Then look at 6, 8, 10, (), 14, 6 + 2 = 8 8 + 2 = 10 10 10 + 2 = 12 12 + 2 = 14, so the second one is 12

4,1, (), 1 / 16,1 / 64. 1 / 6,1 / 2, (), 4 1 / 2,13 1 / 2. 1 / 2,3 1 / 2,7,10,20, (), ()

4,1,1 / 4,1 / 16,1 / 64 ratio sequence, 1 / 4 times decreasing
1 / 6, 1 / 2, 3 / 2, 9 / 2, 27 / 2 equal ratio sequence, 3 times increasing
Molecule + 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2,2 / 2

13 out of 2 and 7.10.20 out of 2

10=13/2+7/2；
20=13/2+7/2+10;
From the third number, the sum of all the previous numbers, then 13 / 2, 7 / 2, 10, 20, 40

Fill in 1 / 2, 1 / 6, 1 / 12, 1 / 30, 1 / 42, (), ()

The rule of denominator is as follows
2=1X2
6=2X3
12=3X4
20=4X5
30=5X6
42=6X7
The next three numbers are:
7x8 = 56, i.e. 1 / 56
8x9 = 72, i.e. 1 / 72
9x10 = 90, i.e. 1 / 90
