Question

Generate the first 5 terms of this sequence:
f(1) = 2 and f(2) = 3, f(n) = f(n - 1) + f(n - 2), for n > 2.
A.2, 3, 5, 7, 9 B.2, 3, 4, 7, 11 C.2, 3, 5, 9, 11 D.2, 3, 5, 8, 13

Answer 1

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.
