Fibonacci

Leonardo Pisano Bigollo (Pisa, c. 1170 – c. 1250) – better known as Fibonacci, was an Italian mathematician, considered “the most talented western mathematician” of the Middle Ages. He united the procedures of the Greek Euclidean geometry with the mathematical calculation tools developed by the Arab and Alexandrian Science.

Fibonacci was the son of rich merchants so he found himself traveling extensively around the Mediterranean coast where he learned traders’ arithmetical systems, realizing the benefits of the Hindu-Arabic system which he introduced in Europe with his Liber Abaci (Book of Abacus or Book of Calculation), completed in 1202.

The sequence starts with the number 0 ,1 and continues as follows:  0, 1, 1, 2, 3, 5, 8, 13, 21, 34… etc. The mathematical rule can be expressed under the form: xn = xn-1 + xn-2…
