(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

N/A

3. The attempt at a solution

By definition,

a_{n}->a iff

for all ε>0, there exists an integer N such that n≥N => |a_{n}- a|< ε

But other than stating and looking at the definitions, I really have no clue how to proceed on this problem.

Any help is very much appreciated!
