Call the consecutive odd numbers
\n" ); document.write( " $\"n\"$ , $\"n+%2B+2\"$ , $\"n+%2B+4\"$ , $\"n+%2B+6\"$ , and $\"n+%2B+8\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"%28+n+%2B+n+%2B+2+%2B+n+%2B+4+%2B+n+%2B+6+%2B+n+%2B+8%29%2F5+=+21\"$
\n" ); document.write( " $\"%285n+%2B+20%29%2F5+=+21\"$
\n" ); document.write( " $\"5n+%2B+20+=+105\"$
