Hello everyone! I remember doing these in calc II, but forgot 99% of it. Here is the question:(adsbygoogle = window.adsbygoogle || []).push({});

Find the interval of convergence for the given power series.

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:

Now i'm confused on what i do now, also u see where i have

|x-6|? Is that right or should it be |x+6| ? Alos is it suppose to be the limit as x-> or n->? Thanks!

I'm using the ratio test btw.
