Answer:
D

Step-by-step explanation:

Given

f(n + 1) = f(n) - 2 with f(1) = 10

To generate the sequence substitute values for n into the recursive formula.

f(1) = 10

f(2) = f(1) - 2 = 10 - 2 = 8

f(3) = f(2) - 2 = 8 - 2 = 6

f(4) = f(3) - 2 = 6 - 2 = 4

f(5) = f(4) - 2 = 4 - 2 = 2

The first 5 terms are 10, 8, 6, 4, 2
