It's the second choice

Step-by-step explanation:

Note that the numbers values increase by 5 .

When n = 0 , we have -9 + 5(0) = -9

when n = 1 it is -9 + 5(1) = -4

when n = 2 it is -9 + 5(2) = 1 and so on.

when n = 15 (the last term) 66 = -9 + 5(15).

We can write the summation as:

n=15

∑ (-9 + 5n)

n=0.
