NO. Odd numbers are not always divisible by 5. Examples: 3 , 7, 9, 11, 13, 17, ... are odd numbers and they are not divisible by 5.
An odd number of odd numbers can't add up to an even number.
They are all odd, and they are all prime numbers
There are the infinitely many negative odd numbers and then there are 1, 3, 5, 7, 9, 11, 13 and 15.
The sum of the first 13 odd numbers is 169.

The numbers are 11, 13, 15, 17 and 19.
The first seven odd numbers are 1, 3, 5, 7, 9, 11, and 13. To find their sum, you can add them together: 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49. Therefore, the sum of the first seven odd numbers is 49.
The odd prime numbers less than 20 are 3, 5, 7, 11, 13, 17, and 19.
The numbers are 9, 11, 13, 15 and 17.
If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)
