Can somebody tell me which document or RFC includes this

It's sort of implied by RFC 793 - the "next sequence number" of a TCP
segment, which is computed by Wireshark as a convenience to the user,
is the sequence number that would be used for the first byte of data
following that segment. As sequence numbers are assigned, well,
sequentially, and as they count bytes, if the sequence number of a TCP
segment is N, and the segment has M bytes of data in it, the sequence
number of the first byte of data following that segment would be N+M.
