What is the next number in the Fibonacci sequence: 1, 1, 2, 3, 5, 8, ...?

Each term after the first two is the sum of the two previous terms. With 5 and 8 at the end, the next term is 5 + 8 = 13, so the next number is 13. The other options don’t fit this rule: 11 isn’t the sum of the two preceding numbers, 21 would come after 13 (it’s 13 + 8), and 8 would just repeat the previous value rather than continuing the pattern.
