%N a(n) is the position of the n-th occurrence of the pair "2,2" in A067395 (the first difference sequence of A067368).
%C A comparison of this sequence with A067368 suggests the following conjecture: a(n)=2*A067368(n)+n-1. This has been confirmed for several hundred terms.
%C Above conjecture is true, and it is same as conjecture in Formula section of A067368. - _Altug Alkan_, Sep 26 2018

%e A067395 begins {4,4,4,2,2,4,4,4,4,...}, so a(1)=4.
