You can put this solution on YOUR website!
any even number can be expressed by 2n, (when n is any integer)
any odd number can be expressed by 2k%2B1, (when k is any integer)
The sum of one odd and one even number is 2n%2B%282k%2B1%29=2n%2B2k%2B1=2%28n%2Bk%29%2B1
2%28n%2Bk%29%2B1 is odd number
So one odd and one even number whose sum gives even number DOESN'T EXIST
