 Generally, formula_51 can be called -Fibonacci sequence, and can be called -Lucas sequence.The (1,2)-Fibonacci sequence is

The (1,3)-Fibonacci sequence is

The (2,2)-Fibonacci sequence is

The (3,3)-Fibonacci sequence is

A Fibonacci sequence of order is an integer sequence in which each sequence element is the sum of the previous formula_7 elements (with the exception of the first formula_7 elements in the sequence).The usual Fibonacci numbers are a Fibonacci sequence of order 2.
