Doing that.......for either series...........there is no center number..........well a center number that is an integer that is...........dead center.............the mean.......the average of the prime fund.......is 6.5........ten numbers......is an even number of numbers.....therefore there is not center number........I believe in stats terms................the median..........if I recall..........the mode is the number that appears the most........the mean.........is just the average..........and the median is the middle number.........whether or not it is an average................................in an odd series..........there is a center number.......my hand has 5 fingers...........so I will give the jerks the middle one...........................

But for ten numbers.........there is not middle number.......of the numbers..............which is why 6.5 is the middle....................of course in many series.........the terms are not sequential...........like here................so the middle term............and the average are the same........they are all the same distance apart..............................5.5............is the middle of 1 - 10..........the 1st set of 10 positive integers..........the pf overlaps with.....................

Why might that be imp......................two 5s......................one above, one below.........like sinusoidal waves........like 1/2 + 14.i.....................1/2 = 0.5..........below............14i...............can be seen as 14......just the coefficient.............and 1 + 4 = 5............one below, one above................................



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