What are the rules of how to fill in the back
Everyone's answer is a bit one-sided and can't completely cover the six known numbers
Let's talk about my idea. 1, 3 are singular numbers here, and the rest are even numbers. No matter what method is used, they are out of place, so I finally decided to eliminate them, and the rest are 6, 10, 18, 24 - number them. 6 is the third number, so starting from 6, 6 is 3, 10 is 4, 18 is 5, 24 is 6
Fill in the blanks according to the rule 1.2.6.24
120.720
Fill in the number in brackets, similar to find the rule
1 1 1 1
1 3 5 7
1 5 13 25
1 7 25 ()
Explain the solution
63
Sum of upper, left and upper left numbers
Find the rule and fill in the appropriate number in the brackets. 2,9,3,74,5,5, (), urgent
There is obviously a comma missing in the middle of 74
The odd and even terms are
2,3,4,5,6
9,7,5,3
So the answer is three, six
1,2,2,3,3,5,4,8, (), () find the rule, and fill in the number of the formula in the brackets
5,13
Jump and see, 1, 2, 3, 4, so the next one is 5
Even numbers, 2,3,5,8, are 2 + 3 = 5,3 + 5 = 8, so the next one is 5 + 8 = 13
1=1、2=2、3=、4=24、5=120、6=720…… So n =?
Because 1 = 1,
2=2×1=2、
3=3×2×1=6、
4=4×3×2×1=24、
5=5×4×3×2×1=120、
6=6×5×4×3×2×1=720
So it can be inferred that
n=n!=n*(n-1)*(n-2)*…… *1
