2^3 = 8 even
3^3 = 27 odd
4^3 = 64 even
5^3 = 125 odd
6^3 = 216 even
7^3 = 343 odd.
All are expected 100. So, the answer is 100b because it's no cube.
3^3 = 27 odd
4^3 = 64 even
5^3 = 125 odd
6^3 = 216 even
7^3 = 343 odd.

@Poornima.
You are right. Why can't we consider 343 as an answer guys?
Because that is the only prime no given there, right?

8,27,64,100,125,216,343.
2^3 3^3 4^3 5^3 6^3 7^3 .
100 = 10^2.
2^3 3^3 4^3 5^3 6^3 7^3 .
100 = 10^2.

1 3 6 11 20 39 70.
Diff-2 3 5 9 17 33.
=> Logic is x * 2-1 so 39 is wrong, replace with 37.
