# Limit in Complex Field

Could someone please provide me a little direction.
I'm trying to show this sequence converges

$$x_n=n\left(e^{\frac{2\pi i}{n}}-1\right)$$

I know $$\lim_{n\rightarrow\infty}|x_n|=2\pi i$$, but I have no idea how to arrive at the solution.

This is not a homework question.

The obvious thing to do would be to expand the exponential term as a power series.
