Let $\"n\"$ = the number of band
\n" ); document.write( "members in the shortest row
\n" ); document.write( "The next row will have $\"n+%2B+2\"$ band members
\n" ); document.write( "The next row will have $\"n+%2B+2+%2B+2\"$ band members
\n" ); document.write( "The fourth row will have $\"n+%2B+2+%2B+2+%2B+2\"$ band members
\n" ); document.write( "given:
\n" ); document.write( "There are $\"92\"$ band members
\n" ); document.write( " $\"n+%2B+n+%2B+2+%2B+n+%2B+4+%2B+n+%2B+6+=+92\"$
\n" ); document.write( " $\"4n+%2B+12+=+92\"$
\n" ); document.write( " $\"4n+=+80\"$
\n" ); document.write( " $\"n+=+20\"$
\n" ); document.write( "The shortest row has 20 members\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
