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.

For the first one - I can even conclude that 343 is the answer because it is the only prime number. Why is that also not a valid answer?
