If wrapping is allowed (reasonable), then the sequence is neither strictly 
nor monotonically increasing.  I have once offered the definition 
"unitarily increasing" to mean "each new issue increases by one", but that 
is an invented term, and one still needs to specify either the number of 
digits or the maximal value if wrapping is an expectation.  Technically, 
"0,1,0,1,..." would qualify in Z2.
