Robert Israel, Table of n, a(n) for n = 0..4759
Index entries for linear recurrences with constant coefficients, signature (0,-1,1,5,3,2,1).
FORMULA
EXAMPLE
a(5) = F(5)*F(6) mod L(7) = 5*8 mod 29 = 11.
MAPLE
F:= combinat:-fibonacci:
L:= n -> F(n-1)+F(n+1):
seq(F(n)*F(n+1) mod L(n+2), n=0..20);
MATHEMATICA
a[n_] := Mod[Fibonacci[n] * Fibonacci[n + 1], LucasL[n + 2]]; Array[a, 50, 0] (* Amiram Eldar, Jan 26 2022 *)
