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

Best ResponseYou've already chosen the best response.0So 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 ∞/∞.

Best ResponseYou've already chosen the best response.0There are more rigorous mathematical ways to show that, but do you understand the reasoning?

Best ResponseYou've already chosen the best response.0I see. I mean, I understand it conceptually. Just not sure how I "show" that when I'm writing things out. "infinity/infinity" for work shown?

Best ResponseYou've already chosen the best response.0And if it is infinity over infinity, then how would that converge to 0?

Best ResponseYou've already chosen the best response.0Are you familiar with calculus derivatives and L'Hopital's rule?
