$\sum_{n = 1}^{\infty} \frac {(27 + \pi)}{n^{0.5}} = (27 + \pi) \sum_{n = 1}^{\infty} \frac 1{n^{0.5}}$

use the p-series test

3. P-series tests show the sum is convergent if the exponent is greater than one.

4. thus, the series is divergent..

Our help to the OP was a piecewise cumulative distribution function split in three different intervals!
