Hello everyone, i'm confused (as usual). I think i found the radius of convergence but then waht do i do to find the interval on which it converges?

The directions says:

Find all the values of x such that the given series would converge.

The series is convergent

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

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

Here is my work:
