Determine Whether the Series Is Convergent or Divergent by Expressing $s _ { n }$

Multiple Choice

Determine whether the series is convergent or divergent by expressing $s _ { n }$ as a telescoping sum. If it is convergent, find its sum. $\sum _ { n = 1 } ^ { \infty } \frac { 10 } { n ^ { 2 } + 2 n }$ .

A) $\frac { 15 } { 2 }$
B) diverges
C) $2$
D) $\frac { 1 } { 10 }$
E) $\frac { 2 } { 15 }$
