Answer 2

An odd number can be generalized as 2n+1 where n is a natural number including zero.

 

• A number is defined as an odd number if the units digit is not divisible by 2. (OR) If the ones place ends by 1, 3, 5, 7, Or 9, then, it is considered as an odd number.

Consider, the odd number series 1,3,5,7,9, and so on,

• The first odd number 1 can be also written as,

= > 1 = 2 x 0 + 1,

• The second odd number 3 can also be written as,

= > 3 = 2 x 1 + 1,

• The third odd number 5 can also be written as,

= > 5 = 2 x 2+ 1,

• The fourth odd number 7 can also be written as,

= > 7 = 2 x 3 + 1.  

• In general, the nth odd number can be written as,

= > nth odd term = 2 x (n-1) +1,

= > Mathematically, an odd number can be represented as 2n+1 form.

Therefore, the mathematical form of an odd number is 2n+1.
