halp /sci/!

i've got a calc 2 test tomorrow and this is on the practice test. i have no idea how to figure it out.

>Say whether the series converges or diverges
>sum(2^k/k!k) from k = 1 to infinity

tests we've covered so far are ratio test, root test, integral test, comparison test, limit comparison test, and divergence test
