Raduis of convergence.

Greetings

I have some problems finding the correct result

My solution:

I puted Y=6x+16

so now will try to find the raduis of convergence of Y

so let's calculate the raduis criteria of convergence:

I would like to know where is my mistake

thank you!

so let's calculate the raduis criteria of convergence:

- We know that Y=6x+16
- Conseqyently -21/6<=x<=-11/6 so the raduis must be 5/3.
**But this is not the solution!**

**Here is the solution of the book**

I would like to know where is my mistake

thank you!
