1. The problem statement, all variables and given/known data
$$\underset{n\rightarrow\infty}{lim}\frac{e^{1/n}+e^{2/n}+e^{3/n}+\cdots+e^{n/n}}{n}$$

3. The attempt at a solution

done something with Riemann sums however didn't get far, other than that i'm not to sure how to evaluate this. any help would be great, thanks (also not sure if i posted in the right place, if i didnt soz.)
