Hint: Show that $\frac{x^{2n}}{(x+n)^{3/2}}\leq \frac 1{n^{3/2}}$, hence the series is _ (fill in the blank) convergent. What about the sum of a series of uniformly continuous functions which is __ (fill in the blank) convergent?

WolframAlpha says:
$\sum_{n=1}^{\infty}\frac{x^{2n}}{(x+n)^{3/2}}= x^2 \Phi\left( x^2,\frac{3}{2},x+1 \right)$, when $|x|<1$. $\Phi(z,s,a)$ gives the Hurwitz Lerch transcendent.
