If you were on V5R4, it sounds like something recursive SQL could perform.
Given that you must compare one value in sequence to the next (or previous
depending on the algorithm) I don't know a quick way other than reading the
sequence in order. With the proper indexes, runtime should be blazing fast.

anybody know of an algorithm, other than brute force, for finding gaps
