I'm assuming that y is some function of x.
You need to look for patterns and perform induction to create some function such that y=f%28x%29
2,4,8,16.. are all powers of two, so let's try that:
y=2%5Ex
And look that, it just so happens that it works for each row.

------
2 = 2^1
4 = 2^2
8 = 2^3
...
...
64 = 2^6

Ans:: a(n) = 2^n
