The three series , , and have termsUse the Limit Comparison Test to compare the following series to any of the above series. For each of the series below, you must enter two letters. The first is the letter (A,B, or C) of the series above that it can be compared to using the Limit Comparison Test. For the second letter, enter C if the given series converges, or D if it diverges. So for instance, if you believe the series converges and can be compared with series C above, you would enter CC; or if you believe it diverges and can be compared with series A, you would enter AD. **1. **

Please help! I am having SUCH a hard time with sum/series, convergence/divergence.

I have no idea where to even begin.

All I know is that 1/n is a harmonic series and diverges. If a function contains that series, it is too divergent.

THANK YOU!!!!
