I have online hw and it tells me if my answer is correct or not. It said that my answer for this problem is incorrect:
Can someone tell me what I did wrong?
Also I might be asking alot of these questions later since I am new to this concept.

If $\lim_{n\to\infty}a_{n+1}/a_n<1$ the series converges, if $\lim_{n\to\infty}a_{n+1}/a_n>1$ the series diverges.
The test gives no information if $\lim_{n\to\infty}a_{n+1}/a_n=1$.
