 OFFSET 1,2 LINKS G. C. Greubel, Table of n, a(n) for n = 1..1000 Index entries for linear recurrences with constant coefficients, signature (1,0,0,0,1,-1). FORMULA From Chai Wah Wu, May 30 2016: (Start) a(n) = a(n-1) + a(n-5) - a(n-6) for n > 6. G.f.: x^2*(x^4 + x^3 + x^2 + x + 4)/(x^6 - x^5 - x + 1). (End) From Wesley Ivan Hurt, Aug 16 2016: (Start) a(n) = a(n-5) + 8 for n > 5. a(n) = n + 2 + 3*floor((n-2)/5). a(n) = (8*n + 4 - 3*((n+3) mod 5))/5. a(5k) = 8k-1, a(5k-1) = 8k-2, a(5k-2) = 8k-3, a(5k-3) = 8k-4, a(5k-4) = 8k-8.
