(In reply to Answer?? by Raika)

That sounds like the most logical sequence I could find.  The sequence found by cheating in the Online Encyclopedia of Integer Sequences has an explanation that I can't understand at all.

As for your solution, perhaps a better explanation is:

The odd terms go in the sequence 1,2,3,4, 4,5,6,7, 7,8,9,10, 10,11,12,13, ... (every fourth term in the counting sequence repeated). The even terms reiterate the whole sequence--that is term 2n = term n.
