Answer
$\Sigma_{n=0}^{\infty}c_{n}x^{n}=c_{0}+c_{1}x+c_{2}x^{2}+......+c_{n}x^{n}+.....$ centered at $x=0$.
Work Step by Step
A power series is an infinite series centered at $x=a$ or $x=0$, which has only one form:
$\Sigma_{n=0}^{\infty}c_{n}x^{n}=c_{0}+c_{1}x+c_{2}x^{2}+......+c_{n}x^{n}+.....$ centered at $x=0$.
