Question

The following function defines a recursive sequence:

f(0) = -3

f(1) = 6

f(n) = -2•f(n -1) - f(n - 2); for n > 1

Which of the following sequences is defined by this recursive function?
-3, 6, -9, -12, …
-3, 20, -95, 480, …
-3, 6, -9, 12, …
-3, -20, -95, -480, …

Answer 3

you have:
\(f(2)=-2*f(1)-f(0) = -2*6 - (-3) = -9\)

Answer 4

now make for n = 3 and find out the answer
