%N After A084937(n) has been computed, let m = largest term so far in A084937. Then a(n) = number of positive odd integers < m that are missing from A084937 at this point.

%C Running count of missing odd numbers in A084937.

%H N. J. A. Sloane, <a href="/A250100/b250100.txt">Table of n, a(n) for n = 1..100000</a>

%e After step 7 of A084937, here is what we have:

%e 1 2 3 4 5 6 7 ... n

%e 1 2 3 5 4 7 9 ... A084937(n)

%e so m = 9, and the missing numbers < 9 are 6 and 8, both even, so a(7) = 0.

%Y Cf. A084937, A249686, A250099. See A249777, A249856, A249857 for another way of looking at this question.
