\n" ); document.write( "(2n+1)^2-(2n+1) is an even number\r

\n" );
document.write( "(2n + 1)[(2n + 1) – 1]
\n" );
document.write( "(2n + 1)(2n + 1 – 1)
\n" );
document.write( "(2n + 1)(2n), or 2n(2n + 1)
\n" );
document.write( "2n is an EVEN NUMBER, and adding 1 to an even number creates an ODD number
\n" );
document.write( "Therefore,  \n" );
document.write( "

\n" );
