Express the sum using summation notation with a lower limit of summation not necessarily 1 and with k for the index of
summation.
-$$4 + \frac { 9 } { 2 } + 5 + \frac { 11 } { 2 } + \ldots + \frac { 15 } { 2 }$$
A) $\sum _ { k = 8 } ^ { 15 } \frac { k } { 2 }$

B) $\sum _ { k = 8 } ^ { 12 } \frac { \mathrm { k } } { 2 }$

C) $\sum _ { \mathrm { k } = 1 } ^ { 15 } \frac { \mathrm { k } } { 2 }$

D) $\sum _ { k = 2 } ^ { 15 } \frac { \mathrm { k } } { 2 }$

The sequence starts with 4, which is $ \frac{8}{2} $, and ends with $ \frac{15}{2} $, indicating that the terms can be represented as $ \frac{k}{2} $ where $k$ ranges from 8 to 15.
