Question

FAN AND MEDAL
The first four terms of a sequence are shown below:

6, 2, -2, -6

Which of the following functions best defines this sequence?

f(1) = 6, f(n + 1) = f(n) + 4; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) - 2; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) - 4; for n ≥ 1

f(1) = 6, f(n + 1) = f(n) + 2; for n ≥ 1

Answer 6

well. 6+4 = 10

so... it didn't use 4 to get to 2 though

Answer 7

and 2 + 4 = 6 not -2

Answer 8

so would it be -2
