**Finding "a" and "b" in an infinite series limit comparison test**

## Homework Statement

[tex]

\sum_{n=1}^\infty \frac{\sqrt{n+2}}{2n^2+n+1}

[/tex]

How do I identify my a_n and my b_n?

In this particular problem you need to use the Limit comparison test which is your "a_n" divided by your "b_n". I know how to solve the problem once these variables are identified, but for each question i attempt to do, i am not seeing a pattern in how to identify your a and b.
