\ \
The series is . \ \
The series is in the form of -series. \ \
-Series test : \ \
If the series where
. \ \
If then the
series converges. \ \
If then the
series diverges. \ \
Consider . \ \
Compare the series with general series. \ \
\Here . \ \
Therefore, the series is diverges since . \ \
Therefore, the series is converges using
-series test.
