Solve the problem.
-If a $a _ { 1 }$ is $4 , a _ { 32 }$ is $\frac { 5 } { 3 }$, and $d$ is $- \frac { 7 } { 93 }$, find $S _ { 32 }$.
A) $\frac { 8425 } { 93 }$
B) $\frac { 272 } { 3 }$
C) $\frac { 544 } { 3 }$
D) $\frac { 2813 } { 31 }$

The sum of an arithmetic sequence is given by $ S_n = \frac{n}{2} (a_1 + a_n) $. Here, $ n = 32 $, $ a_1 = 4 $, and $ a_{32} = \frac{5}{3} $. So, $ S_{32} = \frac{32}{2} (4 + \frac{5}{3}) = 16 \times \frac{17}{3} = \frac{272}{3} $.
