i am guessing the radius is either x or x/2 but i am still not sure..CAN someone help me plz?

PLZ HELP ME...i dont know where to start

Take the ratio of two succesive terms and take the limit n --> infinity. For finite x the limit is zero, which means that the radius of convergence is infinity. In general, the radius of convergence is that value for x you have to substitute in the above limit to make it equal to 1. In this case the limit is zero for all x.

so the radius would be x right?
