MATHEMATICA

r=(1+5^(1/2))/2; h=1/2; s=r/(r-1);

a[n_]:=Floor [n*r+h];

Table[a[n], {n, 1, 120}]  (* A007067 *)

t1={}; Do[If[PrimeQ[a[n]], AppendTo[t1, a[n]]], {n, 1, 600}]; t1

t2={}; Do[If[PrimeQ[a[n]], AppendTo[t2, n]], {n, 1, 600}]; t2

t3={}; Do[If[MemberQ[t1, Prime[n]], AppendTo[t3, n]], {n, 1, 300}]; t3
