EXAMPLE

The differences accrue like this:

1-1

2-1

4-3.....4-1

8-3.....8-1

16-9....16-3....16-1

32-27...32-9....32-3....32-1

64-27...64-9....64-3....64-1

MATHEMATICA

c = 2; d = 3; t[i_, j_] := c^i - d^j;

u = Table[t[i, j], {i, 0, 40}, {j, 0, i*Log[d, c]}];

v = Union[Flatten[u ]]

CROSSREFS
