-$\frac { 1 } { 1 } , \frac { 1 } { 4 } , \frac { 1 } { 9 } , \frac { 1 } { 16 } , \ldots$
A) $a _ { n } = \frac { 1 } { n ^ { 2 } }$
B) $a _ { n } = \left( \frac { 1 } { 2 } \right) ^ { n - 1 }$
C) $a _ { n } = \frac { 1 } { 3 n - 2 }$

The given sequence is $\frac{1}{1^2}, \frac{1}{2^2}, \frac{1}{3^2}, \frac{1}{4^2}, \ldots$, which follows the pattern $a_n = \frac{1}{n^2}$.
