$(1$ point$)$ Use the ratio test to determine whether ${\displaystyle \underset{n=8}{\overset{}{}}}\frac{8^n}{(2n)!},$ converges or diverges.

$($a$)$ Find the ratio of successive terms. Write your answer as a fully simplified fraction. For $n8,$

$\underset{n}{lim}|\frac{a_{n+1}}{a_n}|=\underset{n}{lim}$

$q,$

$($b$)$ Evaluate the limit in the previous part. Enter $$ as infinity and $-$ as $-$infinity. If the limit does not exist, enter DNE.

$\underset{n}{lim}|\frac{a_{n+1}}{a_n}|=$

$$

$($c$)$ By the ratio test, does the series converge, diverge, or is the test inconclusive?

Converges
