A pattern, or sequence, is a set of numbers that are connected in some way. And the numbers in the sequence are called terms. All sequences have a rule. The numbers could count on by three each ...

One set rises gradually, another moderately and the third steeply. Count the number of spirals and you’ll find eight gradual, 13 moderate and 21 steeply rising ones. Fibonacci numbers again.

3 – 1 = 2 6 - 3 = 3 10 – 6 = 4 15 – 10 = 5 If the pattern continues, then the next difference will be +6, meaning that the next term is 21 (15 + 6).

Better known by his pen name, Fibonacci, he came up with a number sequence that keeps popping up throughout the plant kingdom, and the art world, too. A Fibonacci sequence is simple enough to ...
