Dear AnnaStrophic:

Fibonacci Series, in mathematics, series of numbers in which each member is the sum of the two preceding numbers. For example, a series beginning 0, 1 … continues as 1, 2, 3, 5, 8, 13, 21, and so forth. The series was discovered by the Italian mathematician Leonardo Fibonacci (circa 1170-c. 1240), also called Leonardo of Pisa. Fibonacci numbers have many interesting properties and are widely used in mathematics. Natural patterns, such as the spiral growth of leaves on some trees, often exhibit the Fibonacci series.
