Much as it pains me to do this, I will have to move this thread from GD to Math.

Actually I don't think you can get close to it. No matter how big a number you choose, infinity it still infinitely "far" away.You can come arbitrarily close to infinity, but you can never reach it.

your definition is better I like to think of it in the following way:Integral said:Actually I don't think you can get close to it. No matter how big a number you choose, infinity it still infinitely "far" away.

let's say you have a=x/n . You can choose x to be the greatest number your imagination can muster (thus coming arbitrarily close to infinity). lim of a when n -> infinity will always be 0. So as you said, "infinity it still infinitely "far" away".
