In a pineapple, we observe the Fibonacci sequence in the numbers of “eyes” (or flowers) on the pineapple’s outer surface. The way they are naturally arranged is in sets in pairs, threes, fives, eights or thirteens (the Fibonacci sequence). A pineapple is formed by rows of “eyes” that typically end up being 5-8-13 or 8-13-21. In either case, a given row is the sum of the two “previous” rows (5+8=13, and 8+13=21). Therefore, the outer structure of pineapples exhibit a pure form of the Fibonacci sequence.
