Test each of the following series for convergence by either the
Comparison Test or the Limit Comparison Test.
If at least one test can be applied to the series, enter CONV if
it converges or DIV if it diverges.
If neither test can be applied to the series, enter NA.
(Note: this means that even if you know a given series converges
by some other test, but the comparison tests cannot be applied to it,
then you must enter NA rather than CONV.)
