Question

If F(n) is a Fibonacci number and n = 8, which of the following is true?

Options

• F(8) = F(9) + F(10)

• F(8) = F(7) + F(6)

• F(8) = F(10) × F(9)

• F(8) = F(7) – F(6)

Answer 1

F(8) = F(7) + F(6)

Explanation;

Hint:

Given F(n) is a Fibonacci number and n = 8

∴ F(8) = F(7) + F(6) as any term in Fibonacci series is the sum of preceding 2 terms
