Given the two Fibonacci numbers below, which number would follow?

(17) - 1597 and F (18) = 2584

4181

Step-by-step explanation:

The Fibonacci sequence starts with 0 and 1 ... then all other terms are obtained by adding the two previous terms.

0, 1, 1, 2, 3, 5, 8, 13, 21, and so on.

So, if you have any two consecutive terms from the sequence, you can easily find the next one by adding them together:

F (19) = F (17) + F (18)

F (19) = 1597 + 2584 = 4181
