Help with Maple's incorrect

Dear friends,
I could not find my mistake when I use the following computing with Maple.
> restart;
> sum((2*n^2+3*n)/sqrt(5+n^5), n = 1 .. infinity):

> evalf(%);
1.761936848

That is wrong result, since the series is divergent.
Please help me to find out my mistake.
thanks,
Lam
