any even number can be expressed by $\"2n\"$ , (when n is any integer)
\n" ); document.write( "any odd number can be expressed by $\"2k%2B1\"$ , (when k is any integer)
\n" ); document.write( "The sum of one odd and one even number is $\"2n%2B%282k%2B1%29=2n%2B2k%2B1=2%28n%2Bk%29%2B1\"$
\n" ); document.write( " $\"2%28n%2Bk%29%2B1\"$ is odd number
\n" ); document.write( "So one odd and one even number whose sum gives even number DOESN'T EXIST\r
