Question

In power series
the centre is​

Answer 1

Answer:

where the point x0 is called the center of the power series. Consider a function f(x)= ∞∑n=0an(x−x0)n. The domain of this function is the set of those values of x for which the series is convergent. The domain of such function is called the interval of convergence.
