Question

PLEASE HELP BIG GRADE

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

Answers: f(3) = f(2) + f(1) => 3 + 2 = 5

f(4) = f(3) + f(2) => 5 + 3 = 8

f(5) = f(4) + f(3) => 8 + 5 = 13

Therefore the sequence is 2, 3, 5, 8, 13,.....a Fibonacci sequence. :)

Answer 2

@Love_Ranaa that is not in the choices though?

Answer 3
