Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 478, 0, 0, 0, 0, 1).
FORMULA
G.f.: -(x^8-2*x^7+3*x^6-5*x^5+13*x^4+5*x^3+3*x^2+2*x+1) / (x^10+478*x^5-1). - Colin Barker, Nov 20 2013
a(n) = 478*a(n-5) + a(n-10) for n>9. - Vincenzo Librandi, Dec 22 2013
