#### Answer

$\displaystyle \sum_{n=1}^{\infty}(n^{2}-2)$

#### Work Step by Step

We first start with the perfect squares: 1, 4, 9, 16, 25, ... $\qquad$(squares of 1,2,3,...) Starting with n=1, the terms in the sum are $a_{n}=n^{2}-2$, and there is no upper limit on n. Sum = $\displaystyle \sum_{n=1}^{\infty}(n^{2}-2)$
