My answer is
50

Reasoning:
n(0) = 2; n(i) = 2+ n(i-1) + 4*i

*edit* quoting [hidden] tags defeats the purpose of them

Arent you just doubling squares?

In the real world that could be the areas of rectangles whose length is twice the width. ??????????

You may well be right about what's intended, but when someone comes up with a simple mathematical relation (doubling squares) that works it's a bit difficult to say it's "wrong".

It's a fundamental problem with this sort of puzzle, in my opinion.

You are of course correct. Those mathematical explanations are correct. However there is another answer which is not based on a simple mathematical function.

I apologize forkedknight.
