For given power series
the radius of convergence is 2.
For given question,
We have been given a power series 
We need to find the radius of convergence of the power series.
We use ratio test to find the radius of convergence of the power series.
Let 

Consider,

By Ratio test, given power series converges at 
⇒ |x| < 2
So, the radius of convergence is 2.
Therefore, for given power series
the radius of convergence is 2.
