Robert Israel, Table of n, a(n) for n = 0..10000

Index entries for linear recurrences with constant coefficients, signature (1,0,0,0,1,-1).

FORMULA

a(n) = 5n + 26*floor(n/5) = 5n + 26*A002266(n)

G.f.: (5*x+5*x^2+5*x^3+5*x^4+31*x^5)/(1-x-x^5+x^6). - Robert Israel, Apr 02 2017

EXAMPLE

a(0) = 5(0) + 26*floor(0/5) = 0

a(3) = 5(3) + 26*floor(3/5) = 15

MAPLE

seq(5*n + 26*floor(n/5), n=0..200); # Robert Israel, Apr 02 2017

PROG

(Python) a = lambda n: 5*n + 26*floor(n/5)
