The pattern appears to be increasing by multiplying by 3 and then adding 1. Starting with 1, the next number would be 1 x 3 + 1 = 4, then 4 x 3 + 1 = 13, and so on. Therefore, the next number in the pattern would be 40 x 3 + 1, which equals 121.
It is 43 because 31+12 = 43
If you mean: 1 1 2 3 5 8 13 21 then the next number is 13+21 = 34
The pattern is plus 7. So the next number used to be 1.

What would be the next number in this series 15 12 13 10 11 8?
The next number could be 25. +3, +6, +9, +12 etc.
It is 43 because 31+12 = 43
If you mean: 1 2 3 5 8 13 then the next number is 8+13 = 21
If you mean: 1 1 2 3 5 8 13 21 then the next number is 13+21 = 34
21 and 13. The pattern is t(n) = (-n4 + 10n3 - 23n2 + 38n - 12)/12
The pattern is plus 7. So the next number used to be 1.
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
prime numbers - next number is 13
