Index entries for linear recurrences with constant coefficients, signature (20, 20, 20, 20, 20, 20, -210).
FORMULA
G.f.: (t^7 + 2*t^6 + 2*t^5 + 2*t^4 + 2*t^3 + 2*t^2 + 2*t + 1)/(210*t^7 - 20*t^6 - 20*t^5 - 20*t^4 - 20*t^3 - 20*t^2 - 20*t + 1).
a(n) = -210*a(n-7) + 20*Sum_{k=1..6} a(n-k). - Wesley Ivan Hurt, May 05 2021
