The geometric sequences of the reciprocals of the primes equals the harmonic series.......by Euler's product...........with an s of 1...........the number is 2........the next is 3/2.......one and a half........why..................1/1-1/2........on the bottom..........1 - 1/2 = 1/2.................1 over 1/2.........is 2........just multiply the top and bottom by two to get rid of the fraction on the bottom.............2 plays and imp. role and so does 1 and a half..............the length of the 5 and 6 star...
