Seiichi Manyama, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (5,-10,10,-5,1,0,0,0,0,1).
FORMULA
G.f.: (1-x)^4/((1-x)^5 - x^10).
a(n) = 5*a(n-1) - 10*a(n-2) + 10*a(n-3) - 5*a(n-4) + a(n-5) + a(n-10).
PROG
(PARI) a(n) = sum(k=0, n\10, binomial(n-5*k, 5*k));
(PARI) my(N=66, x='x+O('x^N)); Vec((1-x)^4/((1-x)^5-x^10))
