If F502=a and F500=b, create an expression involving a and b for F501.

Question

I would really appreciate it if anyone can help me with this question. I've been stumped with this question for hours now. It deals with the Fibonacci Sequence.

Answer 1

In the Fibonacci sequence, any term (after the first two) is obtained by adding the two preceding terms. So, the third term is the first term plus the second term, and the fourth term is the second plus the third, for example.

So, term 500 + term 501 = term 502.

Thus, b + term 501 = a

term 501 = a - b.
