Question

I need help understanding this problem. Please help!

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, …

Thanks in advance!

Answer 3

f(0) = -5, f(1) = 20
just that, you eliminate 2series, which are left?
