Lucas numbers


The Lucas numbersMathworldPlanetmath are a slight variation of Fibonacci numbersDlmfMathworldPlanetmath. These numbers follow the same recursion:

ln+1=ln+ln-1

but having different initial conditionsMathworldPlanetmath: l1=1,l2=3 leading to the sequence 1,3,4,7,11,18,29,47,76,123,.

Lucas numbers have the following property: ln=fn-1+fn+1 where fn is the nth Fibonacci number.
