smallest positive number
The definition of odd is given by 2n+1, where n is an integer. So if n=0: 2(0)+1 = 0 + 1 = 1 When n is 0, you get the first smallest positive integer, therefore when n is 45 you'd actually get the 46th smallest positive real integer. Therefore, the 45th smallest positive odd number is given by: 2(45-1)+1 = 2(44)+1 = 88 + 1 = 89 Note: the -1 represents offsetting the numbers, because we begin counting at zero. The answer is 89.
