Question

B(1)=−2 b(n)=b(n−1)−7 What's the 3rd term in this sequence?

Answer 1

Answer:

-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
