Question

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, …

Answer 1

$$
f(0)=-5
\\ f(1)=20
\\ f(2)=-4f(1) -3*f(0)

$$

Answer 2

$$
f(0)=-5
\\ f(1)=20
\\ f(2)=-4f(1) -3*f(0)= -4(20) - 3*({-5})

$$

Answer 3

?

Answer 4

crap those question marks are there

Answer 5

does that make sense

Answer 6

Sorry, the question marks are not intentional, just a problem with format

Answer 7

ok :)

Answer 8
