COMMENT
|
All terms of A007950 are odd, therefore all gaps in A007950 have odd length and a(2*k) = a(2*k+1) for k >= 1.
|
|
EXAMPLE
|
First few terms of A007950 are 1,3,5,9,11, ... . The first gap of length 1 is between 1 and 3, so a(1) = 1; the first gap of length 2 is between 5 and 9; it has length 3, so a(2) = a(3) = 5.
