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?
A. -3, 6, -9, -12, …
B. -3, 20, -95, 480, …
C. -3, 6, -9, 12, …
D. -3, -20, -95, -480, …

Answer 2

ok

Answer 3

what

Answer 4

ok,
f(0) = -3 , first term = -3

f(1) = 6, 2nd term = 6
so, as of now our sequence is -3,6

to find nect term, we will use
f(n) = -2•f(n -1) - f(n - 2)

put n= 2 here, what do u get ?

Answer 5

0?

Answer 6

ok

Answer 7

yes!
f(2) = -2 f(1) - f(0)

and you already know
f(1) =6, f(0) = -3
just plug in values!

Answer 8

so the answer isss?

Answer 9

not A

Answer 10

i'm still working it out I'm just stalling

Answer 11

ok

Answer 12

ok so as I said its not A

Answer 13

yea

Answer 14

So the Answer would be C. -3, 6, -9, 12, and so on

Answer 15

ok thnx :)
