## Homework Statement

Question. Did I do this OK?

## Homework Equations

## The Attempt at a Solution

A_n = Ʃ e^(n^2) x^n from n = 1 to ∞

So I tried the root test. After you take the nth root you have x e^n so then I took the limit of this as n-->∞ and I got infinity. I then said OK |x| < 1 for this to converge so the interval of convergence is (-1,1) ?? This OK?
