What is the 26 th smallest positive odd number?

Answer 1

Assuming, by number you mean integer, otherwise this is impossible to solve (i.e., there are an infinite amount of numbers between 0 and 1 alone, e.g. 0.00002, ...., 0.00900208002, etc.).

Let n be any positive integer (0, 1, 2, 3, 4, 5, ...)

The definition of odd is given by 2n+1, where n is an integer.

If n=0: 2(0)+1 = 0 + 1 = 1

When n is 0, you get the 1st "smallest" positive odd integer, therefore when n is 25 you'd actually calculate the 26th smallest positive real integer. The major point here is that you start counting at 0 and not at 1.

Therefore, the 26th smallest positive odd number is given by:

2(26-1)+1 = 2(25)+1 = 50 + 1 = 51

The answer is 51.
