Answer:
C. -11,325
Step-by-step explanation:
- To know the answer, is convenient to replace some values of "n" in the sum
.
- The result would appear after adding up every value of the expression
when n=1,2,3.....,150. - When n=1, the expression takes the value of (-1):
. - When n=2, the expression takes the value of (-2):
. - Following this way, for every n, we will obtain -n, then, the sum will be:
. This sum can actually be expressed as
, which is the result of solving the initial expression of the sum
. - Finally, the sum of n=-1 to n=-150 equals -11,325.
