Answer:

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

Step-by-step explanation:

b(1) = first term = 12

b(n) = b(n - 1) + (-2)

b(n -1) is the term before the nth term

b(n) = b(n - 1) + (-2)

If n = 2

b(1) = 12

b(2) = b(2 - 1) + (-2)

b(2) = 12 - 2 = 10

If n = 3

b(3) = b(2) - 2

b(3) = 10 - 2 = 8

if n = 4

b(4) = b(3) - 2

b(3) = 8 - 2 = 6

If n = 5

b(5) = b(4) - 2

b(3) = 6 - 2 = 4
