Answer 1

The following function defines a recursive sequence:

f(0) = -4

f(1) = 12

f(n) = -3•f(n -1) - 2•f(n - 2); for n > 1

Which of the following sequences is defined by this recursive function?

-4, 12, -28, 60, …

-4, -12, -28, -60, …

-4, 12, -18, 54, …

-4, 12, -18, -54, …

Answer 2

Substitute -4 into your formula and see what you get!

Answer 3

i got C but im not sure its right :/

Answer 4

Well b is obviously wrong since f(1) is given

Answer 5

i knew B and A were wrong i just didnt know from D and C

Answer 6

@camerondoherty we're over here lol

Answer 7

im nawt good with sequences...

Answer 8

sowwy

Answer 9

I can do this one give me a second .

Answer 10

same here:(

Answer 11

f(n) = -3•f(n -1) - 2•f(n - 2); for n > 1
f(3)=-3*(-18)-2*(12)
f(3)=54-24
f(3)=30
neither c or d are correct. lets check the others.
f(3)=-3*(-28)-2*12
f(3)=84-24=60
a is correct

Answer 12

:O
