Comments

The trisection of A017101 = {3 + 8*k}_{k>=0} gives 3*A017077 = {3*(1 + 12*n)}_{n>=0}, {a(n)}_{n >= 0} and A350051 = {19 + 24*n}_{n>=0}. These three sequences are congruent to 3 modulo 8 and to 3, 5, and 1 modulo 6, respectively.

Formula

a(n) = 11 + 24*n = 11 + A008606(n), for n >= 0

a(n) = 2*a(n-1) - a(n-2), for n >= 1, with a(-1) = -13, a(0) = 11.

G.f.: (11 + 13*x)/(1-x)^2.

E.g.f.: (11 + 24*x)*exp(x).
