Question

15,29,56,108,205,400,next term

Answer 1

the next term will be 758

Answer 2

I think the fifth term should be 208

The given series follows the following pattern.

1 x 15 - 0 x 0 = 15
2 x 15 - 1 x 1 = 29
4 x 15 - 2 x 2 = 56
8 x 15 - 3 x 4 = 108
16 x 15 - 4 x 8= 208
32 x 15 - 5 x 16 = 400

The next term --->>
64 x 15 - 6 x 32 = 768

Hence, the next term will be 768
