Group Title
Can someone explain why
An = (2^n)/[3^(n+1)]
has a limit of 0. I'm missing something algebraically, I guess.

So you'll get a number very very very large on the bottom sooner than you get one on the top, so it'll approach (something)/∞ before ∞/(something) or ∞/∞.

There are more rigorous mathematical ways to show that, but do you understand the reasoning?

And if it is infinity over infinity, then how would that converge to 0?
