B (1) = -2 b (n) = b (n-1) - 7

What's the 3rd term in this sequence?

-16

Step-by-step explanation:

You have given the nth term: It is equal to the previous term, less 7.

Thus, b (1) = - 2 (given)

b (2) = b (1) - 7, or b (2) = - 2 - 7, or b (2) = - 9

Then b (3) = b (2) - 7, or b (3) = - 9 - 7 = - 16
