Let n represent an odd integer.
\n" ); document.write( "now since consecutive means, 1,2,3 and in this case we are dealing with odd numbers, so 1,3,5 we have:\r
\n" ); document.write( "\n" ); document.write( "n+(n+2)+(n+4) = some number\r
\n" ); document.write( "\n" ); document.write( "now we know this number is between 21 and 39, so we rewrite this as an inequality.
\n" ); document.write( " 21< n+(n+2)+(n+4) <39 \r
\n" ); document.write( "\n" ); document.write( "now simplify and we get:\r
\n" ); document.write( "\n" ); document.write( "21<3n+6<39
\n" ); document.write( "
\n" );
