Express the sum using summation notation. Use a lower limit of summation not necessarily 1 and k for the index of summation.
-$$5 + 6 + 7 + 8 + \ldots + 22$$
A) $\sum _ { \mathrm { k } = 7 } ^ { 24 } ( \mathrm { k } - 2 )$
B) $\sum _ { k = 5 } ^ { 22 } ( k - 2 )$
C) $\sum _ { k = 3 } ^ { 20 } ( \mathrm { k } - 2 )$
D) $\sum _ { k = 1 } ^ { 17 } ( \mathrm { k } - 2 )$
