Just google for 'Lucas series'. The very first website I found says
"A Lucas Series is a group of numbers that have the property that the next number in the series is always the sum of the previous two. The most famous Lucas Series is the Fibonacci Numbers where the two initial values are both one."

IMO, it seems that you can choose the first two terms in a Lucas series arbitrarily.
