Colin Barker, Table of n, a(n) for n = 0..500
Index entries for linear recurrences with constant coefficients, signature (76,1).
FORMULA
a(n) = 34*A049669(n). G.f.: -34*x / ( -1+76*x+x^2 ). - R. J. Mathar, Sep 30 2013
From Colin Barker, Apr 06 2017: (Start)
a(n) = ((-38 - 17*sqrt(5))^(-n)*(-1 + (-2889 - 1292*sqrt(5))^n)) / sqrt(5).
a(n) = 76*a(n-1) + a(n-2) for n > 1.
