Answer 1

The following function defines a recursive sequence:

f(0) = -5
f(1) = 20
f(n) = -4•f(n -1) - 3•f(n - 2); for n > 1

Which of the following sequences is defined by this recursive function?
-5, -20, -65, -200, …
-5, 20, -92, 372, …
-5, -24, -92, -372, …
-5, 20, -65, 200, ...



The first four terms of a sequence are shown below:

9, 5, 1, -3

Which of the following functions best defines this sequence?
f(1) = 9, f(n + 1) = f(n) - 4; for n ≥ 1
f(1) = 9, f(n + 1) = f(n) + 4; for n ≥ 1
f(1) = 9, f(n + 1) = f(n) - 5; for n ≥ 1
f(1) = 9, f(n + 1) = f(n) + 5; for n ≥ 1
