EXAMPLE
Omega(14 + 2) = 4 = Omega(14) + 2 and 14 is the least k such that Omega(k+2) = Omega(k)+2. Therefore a(2) = 14.
MATHEMATICA
Omega[n_] := Apply[Plus, Transpose[FactorInteger[n]][[2]]]; m = {1}; For[k = 2, k <= 12, k++, l = {}; Do[ If[Omega[i + k] == Omega[i] + k, l = Append[l, i]], {i, 2, 10^5}]; m = Append[m, Min[l]]]; m
