The first four terms of a sequence are shown below.

8, 5, 2, -1

Which of the following functions best defines this sequence?
a. f(1) = 8, f(n + 1) = f(n ) + 3; for n ≥ 1
b. f(1) = 8, f(n + 1) = f(n ) - 5; for n ≥ 1
c. f(1) = 8, f(n + 1) = f(n ) + 5; for n ≥ 1
d. f(1) = 8, f(n + 1) = f(n ) - 3; for n ≥ 1
this is not making any sense..

I'm not sure but the sequence is being subtracted by three

anonymous · Answer

and there's only one answer where the three is being subtracted?
