There seems to be some pertinent information missing in this teaser. You don't specify that the house numbers begin with 1 and that each successive house is numbered with the next possible number which meets all the criteria given. Without these parameters, the answer would not be possible as there are infinite possibilities.
I asumed it went in cronlogical order starting with 1 and i still got it wrong. I thought it was 66.
