Table of n, a(n) for n=1..91.

EXAMPLE

This table shows (x(n),y(n)) for 1<=n<=13:

n..... 1..2..3..4..5..6..7..8..9..10..11..12..13

x(n).. 3.-2..1..4.-1..2..5..0..3..4...1...4..-1

y(n). -1..1..0.-1..1..0..3..1..0.-1...1...0...2

MATHEMATICA

c = 3; d = 8;

x1 = {3, -2, 1, 4, -1, 2, 5, 0, 3, 4, 1};

y1 = {-1, 1, 0, -1, 1, 0, 3, 1, 0, -1, 1};

x[n_] := If[n <= c + d, x1[[n]], x[n - c - d] + 1]

y[n_] := If[n <= c + d, y1[[n]], y[n - c - d] + 1]

Table[x[n], {n, 1, 100}]  (* A194520 *)

Table[y[n], {n, 1, 100}]  (* A194521 *)

r[1, n_] := n; r[2, n_] := x[n]; r[3, n_] := y[n]

TableForm[Table[r[m, n], {m, 1, 3}, {n, 1, 30}]]
