5 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!

ella [17]

Yes, this series converges. We can check using the integral test; we have

$\displaystyle\frac1{25}+\frac1{36}+\frac1{49}+\cdots=\sum_{n=5}^\infty\frac1{n^2}$

and

$\displaystyle\sum_{n=5}^\infty\frac1{n^2}\le\int_5^\infty\frac{\mathrm dx}{x^2}=\frac15$
