Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0, 0, 0, 0, 12236, 0, 0, 0, 0, 1).
FORMULA
G.f.: -(x^8-11*x^7+12*x^6-23*x^5+265*x^4+23*x^3+12*x^2+11*x+1) / (x^10+12236*x^5-1). - Colin Barker, Nov 29 2013
a(n) = 12236*a(n-5) + a(n-10) for n>9. - Vincenzo Librandi, Jan 12 2014
