There aren't any. This is because:\r
\n" ); document.write( "\n" ); document.write( "a + b + c = (1/2)(100a + 10b + c)\r
\n" ); document.write( "\n" ); document.write( "2a + 2b + 2c = 100a + 10b + c\r
\n" ); document.write( "\n" ); document.write( "98a + 8b - c = 0.\r
\n" ); document.write( "\n" ); document.write( "98a + 8b = c\r
\n" ); document.write( "\n" ); document.write( "Since a must be at least 1 (since it's a three-digit number) then c is at least 98, which wouldn't work.
\n" ); document.write( "
\n" );
