# Math Help - Specific Series question.

1. ## Specific Series question.

$Series from 1 of ((x-5)^(1/2)) / (2x^2-2)$

How would you go about solving this? I compared to p series of 1/x^3/2 but idk if that's correct.

What is the question? To determine if the sum converges?

Yes, sorry I'm learning how to use this latex system. It's $\Sigma\frac{\sqrt{n-5}}{2n^2-2}$

And yes, to determine if the sum converges or diverges, but I don't have to find the actual sum, just determine convergence.

Thanks!

4. Compare with $\frac{1}{\sqrt{n^3}}$.

That converges, I assumed that's Bn and the Original function was An, An>Bn and Bn converges, but it doesn't prove that An converges. Am I missing something?

6. Use the limit comparison test.
