Yes, the factors of all odd numbers are odd numbers.
16
How many odd numbers are there from 16 to 30? Seven {7} odd numbers
If this question means "in the interval 0 to 16 inclusive, is the sum of the odd numbers the same as the sum of the even numbers ?" then the answer is no. The sum of the even numbers is eight more than the sum of the odd ones.
Adding three odd numbers will never equal an even number.
There are 7 odd numbers between 16 and 30. To find this, you can subtract the largest odd number less than 30 (29) from the smallest odd number greater than 16 (17), then divide by 2 and add 1. So, (29-17)/2 + 1 = 7 odd numbers between 16 and 30.
16.
