%N Number of distinct prime factors of L(n + F(n)) where F(n) is the Fibonacci number and L(n) is the Lucas number and n >= 1.
%e If n=1 then L(1 + F(1)) = 3 (prime) and so the first term is 1.
%e If n=2 then L(2 + F(2)) = 4 = 2^2 and so the second term is also 1.
%e If n=3 then L(3 + F(3)) = 11 (prime) and so the third term is also 1.
