There is a 19 in the sequence of numbers.........found by taking the diff of squares................



3, 5, 7, 9, 11, 13, 15, 17, 19, 21............that is the same sequence u get by taking the diff of the squares...................................................7 primes out of 10.....................................9, 15, and 21 are the non primes........................the 1st zero is right under 15.........the 2nd one is right over 21.........................odd doncha think?  Other than 9, 15 and 21 all being odd, strange I should say.......................or type.........but anyways............
