There are an infinite number of odd numbers that are divisible by 7. You can calculate an infinite number of odd numbers that are divisible by 7 by multiplying 7 by odd numbers. There are an infinite number of odd numbers. 7 x 1 = 7 7 x 3 = 21 7 x 5 = 3 7 x 7 = 49 7 x 9 = 63 7 x 11 = 77 7 x 13 = 91 7 x 15 = 105 7 x 17 = 119
It is not possible. The sum of 7 odd numbers must be odd while 50 is not odd.
You cannot have 7 odd numbers that will sum to 30.
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.
The only number is odd and that is 7.
