let the consecutive integers be:
\n" ); document.write( " $\"+n+\"$ and $\"+n%2B+1+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( " $\"+n%2A%28+n+%2B+1+%29+=+3%2A%28+n+%2B+n+%2B+1+%29+-+7+\"$
\n" ); document.write( " $\"+n%5E2+%2B+n+=+6n+%2B+3+-+7+\"$
\n" ); document.write( " $\"+n%5E2+-+5n+%2B+4+=+0+\"$
\n" ); document.write( " $\"+%28+n+-+4+%29%2A%28+n+-+1+%29+=+0+\"$
\n" ); document.write( " $\"+n+=+4+\"$
\n" ); document.write( " $\"+n+=+1+\"$
\n" ); document.write( "------------------
\n" ); document.write( " $\"+n+-+4+\"$
\n" ); document.write( " $\"+n+%2B+1+=+5+\"$
\n" ); document.write( " $\"+n%2A%28+n%2B+1+%29+=+3%2A%28+n+%2B+n+%2B+1+%29+-+7+\"$
\n" ); document.write( " $\"+4%2A5+=+3%2A%28+4+%2B+5+%29+-+7+\"$
\n" ); document.write( " $\"+20+=+27+-+7+\"$
\n" ); document.write( " $\"+20+=+20+\"$
\n" ); document.write( "OK
\n" ); document.write( "--------------------
\n" ); document.write( " $\"+n+=+1+\"$
\n" ); document.write( " $\"+n+%2B+1+=+2+\"$
\n" ); document.write( " $\"+n%2A%28+n%2B1+%29+=+3%2A%28+n+%2B+n+%2B+1+%29+-+7+\"$
\n" ); document.write( " $\"+1%2A2+=+3%2A%28+1+%2B+2+%29+-+7+\"$
\n" ); document.write( " $\"+2+=+9+-+7+\"$
\n" ); document.write( " $\"+2+=+2+\"$
\n" ); document.write( "OK
\n" ); document.write( "--------------------
\n" ); document.write( "There are 2 answers:
\n" ); document.write( "1 and 2
\n" ); document.write( "and also:
\n" ); document.write( "4 and 5
\n" ); document.write( " \n" ); document.write( "

\n" );
