There are 20 natural numbers, of which the odd number is more than the even number, and the sum of them is 100, then there are at most 20 natural numbers______ An even number

There are 20 natural numbers, of which the odd number is more than the even number, and the sum of them is 100, then there are at most 20 natural numbers______ An even number

If the odd number is more than the even number, then the odd number should be at least 11; if the sum of 20 natural numbers is even, then the odd number must be even, otherwise the odd number and odd number result in odd number. The odd number must be even, and the odd number should be at least 11. In fact, the odd number should be at least 12, which corresponds to the maximum even number: 20-12 = 8
