EXAMPLE

The even sieve begins: 1, 3, 5, 9, 11, 17, 19, 25, 27, 35, 37 and between 1&3 there is a gap of 2;

the difference between 3&5 is also 2, but between 5&9 the difference or gap is 4; etc.

MATHEMATICA

lst = Range[10^6]; i = 2; While[i <= (len = Length[lst]), lst = Drop[lst, {i, len, i}]; i+=2]; l = {}; d = 0; Do[a = lst[[n + 1]] - lst[[n]]; If[a > d, d = a; AppendTo[l, lst[[n]]]], {n, Length@lst - 1}]; l
