Starting to look at Convergence of sequences and given an example without a solution. The solution would really help my understanding of what's going on here:

Define what is meant by saying converges to the limit l as n goes to infinity. Show that converges to as n tends to infinity.

Now I know you can pull out the fraction and show that the rest tends to 1 (right?), simple enough you can already see the right there but how do you show this? Basically that l =
