Look at the following numbers: -7, 0, 7, 14
Which pair of numbers has a sum of 0?
O 0,7
O-7,7
07, 14
O-7, 14

Arithmetic sequence is -5, x, y, z, -25
Now, a = -5 
a(n) = a + (n - 1)d
a(5) = -5 + (5 -1)d
a(5) = -5 + 4d = -25
4d = -25 + 5
d = -20/4
d = -5

So, a(2) = -5-5 = -10
a(3) = -10-5 = -15
a(4) = -15-5 = -20

Your Sequence is -5. -10, -15, -20, -25

In short, Your Answer would be Option A

Hope this helps!
