 OFFSET 1,2 LINKS Colin Barker, Table of n, a(n) for n = 1..500 Index entries for linear recurrences with constant coefficients, signature (121,-2220,12100,-10000). FORMULA From Colin Barker, Oct 03 2015: (Start) a(n) = 121*a(n-1)-2220*a(n-2)+12100*a(n-3)-10000*a(n-4) for n>4. G.f.: x / ((x-1)*(10*x-1)^2*(100*x-1)). (End) PROG (PARI) Vec(x / ((x-1)*(10*x-1)^2*(100*x-1)) + O(x^30)) \\ Colin Barker, Oct 03 2015 CROSSREFS Cf. A109242, A000292, A002620, A059259, A094028.
