Answer:
-135
Step-by-step explanation:
The summation notation of 10∑n=2 -2n-3.
We can find the values by substituting n into -2n-3.
Let's begin where n = 2
-2(2) - 3 = -7
-2(3) - 3 = -9
-2(4) - 3 = -11
-2(5) - 3 = -13
-2(6) - 3 = -15
-2(7) - 3 = -17
-2(8) - 3 = -19
-2(9) - 3 = -21
-2(10) - 3 = -23
This gives us:
-7 + -9 + -11 + -13 + -15 + -17 + -19 + -21 + -23 = -135
