First odd number greater than 20 is 21 Last odd number less than 200 is 199 → number of odd numbers between 20 and 200 is (199 - 21) ÷ 2 + 1 = 90
There are 8 odd numbers less than 50 that are divisible by 3 They are 3, 9, 15, 21, 27, 33, 39, and 45.
21, 23 ... (19, both numbers would be odd) Do you know what odd and even means?
The even whole numbers greater than 21 and less than 28 are: 22, 24 and 26
A list of odd numbers that are not prime would include numbers that are composite, meaning they have factors other than 1 and themselves. Examples of odd composite numbers include 9, 15, 21, 25, and 27. These numbers can be divided by factors other than 1 and the number itself, unlike prime numbers which can only be divided by 1 and the number itself.

All odd numbers are the sum of two consecutive numbers. Odd multiples of 7 less than 25 are 7 and 21.
There are 8 odd numbers less than 50 that are divisible by 3 They are 3, 9, 15, 21, 27, 33, 39, and 45.
The odd composite numbers lower than 30 are:9 15 21 25 27
9, 15, 21, 25, 27
21, 23 ... (19, both numbers would be odd) Do you know what odd and even means?
That's an infinite list starting with 25, 23, 21, 19 and going on forever.
If an odd number has more than two factors then it is a composite number but if it has only two factors then it is a prime number. Although all prime numbers are odd except for 2 many more odd numbers are composite numbers having more than two factors as for example 21 is an odd number whose factors are 1, 3, 7 and 21.
The even whole numbers greater than 21 and less than 28 are: 22, 24 and 26
How many numbers less than 700 are divisible by both 15 and 21?
23, 25, 27, 29... add two forever.If you want a more mathematical notation, the nth odd number after 21 is2n + 21I don't know how else to say it, because there are infinite odd numbers above 21.
The sum of any four odd numbers will never be equal to an odd number.
