A recursive function is shown below:

f(1) = 5 and f(n) = f(n - 1) - 6; n 1

Which of the following lists the terms in the sequence defined by this recursive function?

A. 5, 1, 7, 13, 19, ...

B. 5, -1, -7, -13, -19, ...

C. 5, 11, 17, 23, 29, ...

D. 5, -11, -17, -23, -29, ...

I think the answer is A.

well, you already know what f(1) is 
so plug in numbers greater than one in to the function, and you will see the sequence
