B (n) = 1 (-2) ^n-1

What is the fourth term in the sequence?

-8

Step-by-step explanation:

If you want to find the fourth term in the sequence, or b (4), then you just plug in the value 4 for n, resulting in

b (4) = 1 (-2) ^ (4-1).

Simplifying, we get

b (4) = 1 (-2) ^3

=1 (-2*-2*-2)

=1 (-8)

=-8
