What is Meant by Radius of Convergence?

We know that the power series will converge at its centre of convergence at some interval. If the power series converges on some interval, then the distance from the centre of convergence to the other end of the interval is called the radius of convergence. The radius of convergence of a power series can be determined by the ratio test. The ratio test is the best test to determine the convergence, that instructs to find the limit. This test predicts the convergence point, if the limit is less than 1.
