Which sequence is generated by the function f (n 1) = f (n) - 2 for f (1) = 10? (a) - 10, - 12, - 14, - 16, - 18, ... (b) - 2, 8, 18, 28, 38, ... (c) 8, 18, 28, 38, 48, ... (d) 10, 8, 6, 4, 2, ...

You skiped one operator.

I assume that the function is f (n+1) = f (n) - 2.

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

So the sequence, is 10, 8, 6, 4, 2, ... [option d]
