Formula

a(n) = floor(n*(1+sqrt(5))/Pi).

Example

For n = 1000 we have that floor(1000*(1+sqrt(5))/Pi) = floor(1000*1.0300724296...) = floor(1030.0724296...) so a(1000) = 1030.

Maple

A277112:=n->floor(n*(1+sqrt(5))/Pi): seq(A277112(n), n=0..100); # Wesley Ivan Hurt, Oct 31 2016

Mathematica

f[n_] := Floor[n*(1+Sqrt[5])/Pi]; Array[f, 100, 0]
