1. The problem statement, all variables and given/known data

Find the limit as n tends to $\infty$ of:

$\frac{(-1)^n}{n}$

2. Relevant equations

3. The attempt at a solution

I know that (-1)^n alternates between 1 and -1.
I also know that the limit of 1/n is 0. But I don't know how to compute the above limit.
Any ideas will be appreciated. Thank you.

Think about what each sequence is in between.
