im stuck with a question on proving a limit of a sequence. Here it is:
Use the epsilon-N definition of a limit to prove that:
lim(n>infinity) n+5/n^2 + 2 = 0.
For epsilon = 1/25 give N such that for all n>=N it follows that:
|n+5/n^2 + 2| < epsilon.
Not sure how to start really. Any help would be appreciated. Thanks
