2. It is quadratic, not exponential. A 10x10 crossword has 100 squares, a 20x20 crossword has 400 squares.

you could just have said google mipmapping that would have been enough

So what's the answer? As far as I'm concerned, the series converges rapidly and every additional term gains a decimal place. Therefore, except for the possibility of rolling the 'current' place to the next value, later values cannot affect the leading digits of the early values. But I just wrote a program to do the sum. It turns out that REDDemon was correct. It appears to be exactly 1 1/3.

But the original figures are interesting. 4 + 4/3 = 4 x 4/3.

Yes, this sum converges to 1/3 (or 4/3 of you take the initial 1 into account).
