Conjectures:

(1) a(n+1)-a(n) is in (2,3,4,5,6} for every n, and each of these differences occurs infinitely many times.

(2) Limit_{n->oo} a(n)/n = (3/2)*(1+sqrt(3)).

(3) Let d(n) = a(n) - A352673(n); then d(n) = 0 for infinitely many n, but {d(n)} is unbounded below and above.

Example

The two Beatty sequences, (1,3,5,6,8,10,12,13,15,17,19,20,...) and (2,5,8,10,13,16,19,21,24,...), share the numbers (5,8,10,13,19,24,...).

Mathematica

z = 200; r = Sqrt[3]; s = 1 + Sqrt[3];
u = Table[Floor[n r], {n, 1, z}]    (* A022838 *)
v = Table[Floor[n s], {n, 1, z}]    (* A054088 *)
Intersection[u, v]  (* A352676 *)
