ODD NUMBER:An odd number is an integer which is not a multiple of two. In other words, an integer that when divided by two, leaves a remainder (of 1). We can also understand the odd number as; it is the number when divided by number 2, the result is always infraction.

The odd number may be positive or negative because integers are from the range negative infinity(- ♾) to positive infinity(+ ♾)

1. smallest positive odd number is 1(one); it Means 1 is the first odd number

2. zero(0) is not 1st odd number

3. Yes negative one(-1) is also an odd number

5. Zero (0) is not an odd number because when we divide it by 2 it becomes zero that is an integer, not a fraction.

6. One(1) is the smallest odd number

7. Not confirm

A number which cannot be divided by 2 is called as an odd number. In other words, a number of form (2k+1), where k= integers, are called odd numbers.

Number 1 is the first positive odd number

If odd numbers are divided by 2, the result or remainder should be a fraction or 1.

Odd Number can be positive(-) or negative(-)

Example: −13, 1, 17, -35, -133 are all odd numbers.

Number Range from 1 to 50 = 25 No. of Odd Numbers

Number Range from 1 to 100 = 50 No. of Odd Numbers

Number Range from 1 to 1000 = 500 No. of Odd Numbers
