Question

The first four terms of a sequence are shown below.

7, 4, 1, -2

Which of the following functions best defines this sequence?

f(1) = 7, f(n + 1) = f(n) + 3; for n ≥ 1

f(1) = 7, f(n + 1) = f(n) - 3; for n ≥ 1

f(1) = 7, f(n + 1) = f(n) - 4; for n ≥ 1

f(1) = 7, f(n + 1) = f(n) + 4; for n ≥ 1

Answer 1

B?

Answer 2

eep idk

Answer 3

Answer 4

f(1+1) = f(2) - 3 = 1

f(2+1) = f(3) - 3 = -2

Answer 5

I think it should've been f(0+1) = f(1) which is 7 - 3 which is 4.

Answer 6

@Lena772 you get it? 4 is f(2) - 3 is 1
f(3) is 1 - 3 is -2

Answer 7

no :/
