Please solve #7. Subject: Real Analysis, Topic:
7. Suppose that the sequence (|c. /Call ) converges to a real number r. Prove that r is the radius of convergence of the power series Jo c.(x -a) (be sure to properly handle the special case r = () On the other hand, prove that if the above sequence diverges to co, then the radius of convergence of the power series is OC
