WebThe radius of convergence is the distance from our independent variable (x) to either end of the interval of convergence. In other words, it is half the length of the interval of convergence. WebThis means that the interval (x0 − r,x0 +r) (the interval of convergence) is the interval of the values of x for which the series converges, and there are no other values of x for which this happens, except for the two endpoints x+ = x0 +r and x− = x0 −r for which the convergence has to be tested case-by-case.
