Question

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, 11, 17, 23, 29, ...

B: 5, -11, -17, -23, -29, ...

C: 5, -1, -7, -13, -19, ...

D: 5, 1, 7, 13, 19, ...

Answer 1

9514 1404 393

Answer:

C: 5, -1, -7, -13, -19, ...

Explanation:

You need look no further than the second term. That term will be ...

f(2) = f(1) -6

f(2) = 5 -6 = -1 . . . . matches sequence C
