Question:

Determine whether the series {eq}\sum_{n=1}^{\infty} 9n^{-0.5} {/eq} converges or diverges, Identify the test used

P-Series Test:

A p-series is a series in the general form {eq}\displaystyle \sum_{n=1}^{\infty} \frac{1}{n^p} {/eq} where p is a constant real number. A p-series converges if and only if p is larger than 1.

This result can be proven by using the integral test and the divergence test.

We have a p-series {eq}\displaystyle \sum_{n=1}^{\infty} 9n^{-0.5} = \sum_{n=1}^{\infty} \frac{9}{n^{0.5}} = \sum_{n=1}^{\infty} \frac{9}{n^{...
