Question

MEDAL FOR ANSWER

Generate the first 5 terms of this sequence:

f(1) = 1 and f(2) = 2, f(n) = f(n - 1) + f(n - 2), for n > 2.

1, 2, 3, 4, 5

1, 2, 3, 5, 7

1, 2, 3, 5, 8

1, 3, 5, 7, 9

Answer 1

It tells you what f(1) is
and it tells you what f(2) is

It also tells you how to calculate the result when n>2

So for n = 3 it tells you
f(3) = f(2) + (f(1)

then
f(4) = f(3) + f(2)
f(5) = f(4) + f(3)

SO start with f(3) since you already know f(1) and f(2)
THEN you can work on to f(4) and f|(5)

you then have your five terms.

Answer 2

it would be A?

Answer 3

I think that is a guess. Please work through the calculations as I showed above:

First
f(3) = f(2) + (f(1)
So calculate that (you know f(1) and f(2) from the question....

Answer 4

And gone offline as soon as I asked for some input.... :-(

Answer 5

sorry ^^ it would be C?

Answer 6

I am not going to confirm or deny your guesses.

Have you worked out the values as indicated above?

Show a little of your work and I will let you know if it's correct
