B can't be the answer. @Pandemonium
no wait let me fix this real quick
i got C but id check with someone else to be sure
Please explain how you got the answer
So did you just guess?
No my teacher is here helping me and even he's confused what the question is asking but he's trying different methods to find the answer
It's florida virtual school, so I wouldn't be surprised if it was entirely wrong.
@pooja195 please help
yea, but me him decide to eliminate the worst possible answers and we got rid of A and B
so your left with C and D
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 ?
-2, but that must be wrong
you just replace "n" by "2" there, to get f(2)
f(2) = -2 f(1) - f(0) and you already know f(1) =6, f(0) = -3 just plug in values!
you need to find f(3) too! f(3) = - 2f(2) - f(1) = - 2(-9) -6 = 18-6 = 12
That's what I did. Idk how I got such a bogus answer. What did you get?
Well A isnt matching and B isnt either
Can you do it for f(4)? I'd probably get it wrong
no that'll probably mess it up but u can try and see if u find a good answer
I got -13, but it's obviously wrong
yea, well my best possible answer would have to be D
its the only one close to matching what me and my teacher got but to sure try to find other possible solutions
so yea its either gonna be C or D
my best guess would be D but i aint 100% sure
