Clark Kimberling, Table of n, a(n) for n = 1..10000

a(n) = floor(n*r) - floor(n*r - r), where r = 1 + sqrt(5), n >= 1.

a(n) = A188187(n) + 3, as follows right from the definitions. - Michel Dekking, Sep 02 2019

z = 500; r = 1+Sqrt[5]; b = Table[Floor[k*r], {k, 0, z}]; (* A276854 *)

Differences[b] (* A276863 *)
