# Luca's numbers....

Just like Fibonacci numbers , there are $$\color{Blue}{Luca's}$$ numbers... They are defined by following recurrence relation. $L_0=2$ $L_1 =1$ $\text{and}$ $L_n = L_{n-1} + L_{n-2}$

Find the value of $$\displaystyle \sum_{n=0} ^{10} L_n$$

Note :- I read about Luca's numbers at this problem in the tag recurrence relations, and i think the same thing as why the maker had chosen $$L_{10}$$ as asked answer, the same is why I also have chosen it to be sum till 10. After you get the answer, you'll come to know it, $$\color{Red}{\text{the answer number looks very good.}}$$
