For the given general term an, write an expression using $\Sigma$ to represent the indicated p to represent the indicated partial sum.
-$a _ { n } = 8 n,$ fourth partial sum
A) $\sum _ { i = 5 } ^ { 5 } 8 i$
B) $\sum _ { i = 1 } ^ { 5 } 8 i$
C) $\sum _ { i = 1 } ^ { 4 } 8 i$
D) $\sum _ { i = 0 } ^ { 4 } 8 i$

The fourth partial sum involves summing the first four terms of the sequence, which is correctly represented by $\sum _ { i = 1 } ^ { 4 } 8 i$, starting from the first term (i=1) and ending with the fourth term (i=4).
