# Convergence Test Problem

## Homework Statement

Determine whether the series converges:
1/(sqrt(k+5))

## Homework Equations

well i think i'm supposed to use the integral test, which has you take the integral of the series and the limit too..

## The Attempt at a Solution

.. i'm just not sure how to begin, for some reason i'm completely BLANKING on how to take limits.. i know that the series diverges, but i dont know how to actually get that answer.

There is also that for all k, $$\frac{1}{\sqrt(k+5)}>\frac{1}{k+5}$$ and $$\sum \frac{1}{k+5}$$ is essentially the harmonic series. :uhh:
