Mark,

a = 0;
Table[If[MatchQ[i, 3 | 5 | 9 | 18], a = a + i], {i, 20}]

could we have a more practical way than this way of choosing some numbers of
the
choice:

a = 0;
Table[If[i == 3 || i == 5 || i == 9 || i==18, a = a + i], {i, 20}]

ie: i wish if it is possible like this:
If[i==3 ||5 ||9||18, ...]

Thanks very much
mark
