Hello, I need help with this series:

The instructions are: Find all the values of x such that the given series would converge. The series is convergent

from , left end included (enter Y or N):

to , right end included (enter Y or N):

Now, I used the ratio test but I got suck with the square root of n, could someone show the steps to solve the series with the ratio test? I know after the values are found you put in each value of x in the series then solve using a test like the limit comparison test to see if it converges so that you know if it is included for the values.

Thanks,

Matt
