2^3=8.
3^3=27.
4^3=64.
5^3=125.
6^3=216.
7^3=343.
But after 4^3 they gave 10^2=100 so that one is odd one.
3^3=27.
4^3=64.
5^3=125.
6^3=216.
7^3=343.
But after 4^3 they gave 10^2=100 so that one is odd one.

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.

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.

Logic : 2^3, 3^3, 4^3, 5^3, 6^3, 7^3.
So 100 is odd one.
