7/6 is not dead center in the 1st 5.........but it is not one of the ends either.......................13 comes from overlapping 7 from the prime fundamental with a 6 on the number line.......so many 6s and 7s............65.....................6.5..................dead center between 6 and 7.................and the average or dead center.............same thing.....................in the series of 2 - 11.................

In the 1st instance........of overlapping the prime fundamental w/ the 1st ten positive integers...................6 is more or less in the middle...........................from 1 - 10................it is just after the center...........which is 5 of course......................


...........(2/1)(3/2)(5/4)(7/6)(11/10).................
