Answer:

D. 10, 8, 6, 4, 2, ...

Step-by-step explanation:

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

This means that each term is the previous term subtracted by 2,

f(1) = 10

This means that the first term of the sequence is 10.

Thus, the sequence is:

10, 8, 6, 4, 2, ...

Thus the correct answer is given by option D.
