What a great question! I don't think I've ever seen an answer to this
either.  If I had to guess, I would say that it is probably a pointer to the
adjacency table.  I checked some of my routers and found that usually the
numbers appear to be sequential in nature, starting with zero and working
their way up incrementally.  However, I have a router that has some numbers
that are skipped:
IP-EIGRP neighbors for process xxx
H   Address                 Interface   Hold Uptime   SRTT   RTO  Q  Seq

I checked some of the texts I have on EIGRP and even the Zinin book doesn't
cover this field.
