FORMULA
Observation : a(n+1)-a(n) = 2, 4 or 6 for every n, a(n)=4n+O(1) and more precisely it seems that abs(a(n)-4n)<=7. Is the sequence a(n)-4n ultimately periodic ? Benoit Cloitre, Aug 10 2003
EXAMPLE
For m = 1 we get 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, ...
For m = 7 we get 7, 11, 17, 27, 43, 69, 111, 179, 289, 467, 755, ...
