2^1, 2^2, 2^3, 2^5, 2^9 ------>this is the series
1 2 3 5 9 ------>these are the powers
1 1 2 4 ------>this is the increment of powers (every term is sum of those previous ones)
the next power increment will be 1+1+2+4=8
8+9=17

2*2 =4 -> second #
4*2 =8 -> third # -> 2 gets from 1*2
8*4=32 -> fourth # -> 4 gets from 2*2
32*16=512 -> fifth # -> 16 gets from 4*4
512*256 =131,072 -> sixth # -> 256 gets from 16*16
so, the sixth # is 131,072

Are you sure that last given term is 512 and not 256???
If it was 256 then it's
2^k where k is 1,2,3,5,8,13,21, etc.

f(n+1)=n^2/2
The next number is 512^2/2, or 131072.

Please doublecheck if there is a number between 32 and 512.
