Question

What is the next number in the sequence? 3, 7, 15, 31, 63

Answer 1

Hey there!!

Okay this is the sequence...

3 --> 7 --> 15 --> 31 --> 63
4 8 16 32

The increments increase each time by 2x... so the next increment would be 64

then 63 + 64 = 127 <----- This is the next number in the sequence


I hope this helps! ^__^

Answer 2

Ok so basically it's doubling the number you add on:
3 + 4 = 7
7 + 8 = 15
15 + 16 = 31
31 + 32 = 63
63 + 64 = 127
