The series is $\"\"$ . \ \

The series is in the form of geometric series. \ \

Geometric series: \ \

The geometric series $\"\"$ is converges if and only if the value of $\"\"$ . \ \

Compare the series with general form. \ \

Here $\"\"$ and $\"\"$ . \ \

The value of $\"\"$ . \ \

The series is converges absolutely. \ \

Therefore, the series $\"\"$ is converges using geometric series test. $\"\"$ \ \

The series $\"\"$ is converges using geometric series test.
