.
- The result would appear after adding up every value of the expression
- 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.
