The series $$\sum_{n=1}^\infty \frac1{(5 n+2)^2}$$ is convergent.

(A). According to the Remainder Estimate for the Integral Test, the error in the approximation $s\approx s_n$ (where $s$ is the value of the infinite sum and $s_n$ is the $n$-th partial sum) is
$|s-s_n| \le$

(B). Find the smallest value of $n$ such that this upper bound is less than 0.0008 .
$n =$
