Assuming you don't allow a zero in the tens place (02,04,...,08) then
\n" ); document.write( "there are 90 2 digit numbers available from 10 to 99.
\n" ); document.write( "Half are even, half are odd.
\n" ); document.write( "Of those 45 even numbers, the ones that start with an odd number will sum to an odd number since odd plus even equals odd.
\n" ); document.write( "1X
\n" ); document.write( "2X
\n" ); document.write( "3X
\n" ); document.write( "4X
\n" ); document.write( "5X
\n" ); document.write( "There are 5 sets of 5 even 2 digit numbers that start with an odd number or 25.\r
\n" ); document.write( "\n" ); document.write( "
