An odd number is an integer which is not a multiple of two. If it is divided by two the result is a fraction. One is the first odd positive number. The next four bigger odd numbers are three, five, seven, and nine. Some sequential odd numbers are: {1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35} And so on.

An integer that is not an odd number is an even number. Some sequential even numbers are: {0,2,4,6,8,10,12,14,16...} If an even number is divided by two, the result is another integer. On the other hand, an odd number, when divided by two, will result in a fraction.

Since odd and even numbers are defined only in reference to the set of integers (..., −3, −2, −1, 0, 1, 2, 3, ...), all negative numbers can also be either odd or even.

To find the set of odd integer numbers, we use 2N+1 where N is any integer.

The below are odd numbers up to 100. Given for reference purposes.

1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59,61,63,65,67,69,71,73,75,77,79,81,83,85,87,89,91,93,95,97,99 Odd numbers are those that are not divisible by two.so negative numbers that are below 0 are like -1,-3,-5,-7.....Etc.
