An odd number of odd numbers can't add up to an even number.
odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
In the same way that and odd plus and even is always odd. For example, 7*3 = (7+7) odd + odd = even , then add +7, apply rule that odd + even = odd and get that it equals 21.
odd
Starting with 7, every other multiple is odd.

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.
How many odd numbers are there from 16 to 30? Seven {7} odd numbers
Only 1/7 of odd numbers divide by seven, so 6/7 of them do not. That makes about infinity odd numbers altogether.
I was able to get the number 30 by adding 4 odd numbers 3 + 7 + 5 + 15 = 30 But i can't add 5 odd numbers to get 30
7
Can not be done! An odd number of odd numbers will ALWAYS add up to an odd number.
Odd numbers are numbers that cannot be divided by two without getting a decimal. 5, for example, is an odd number because if you divide it by 2, the answer is 2.5 and this answer contains a decimal.The number 7 is therefore an odd number.
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number, but your result will be odd, no matter what 7 odd numbers you choose.

It is not possible. The sum of 7 odd numbers must be odd while 50 is not odd.
