Index entries for linear recurrences with constant coefficients, signature (456303,-456303,1).
FORMULA
a(n+2) = 456302*a(n+1)-a(n)+18023850.
G.f.: 79*x*(-97-228151*x+98*x^2) / ( (x-1)*(x^2-456302*x+1) ). - R. J. Mathar, Nov 27 2011
a(n) = 79*A145309(n). - R. J. Mathar, Nov 27 2011
EXAMPLE
a(1)=7663 because the first relation is : (7663+79)^3-7663^3=118579^2.
