Let $\"n\"$ , $\"n%2B1\"$ , and $\"n%2B2\"$ be the integers.
\n" ); document.write( " $\"%28n%2Bn%2B1%2Bn%2B2%29%2F3=5\"$
\n" ); document.write( " $\"3n%2B3=15\"$
\n" ); document.write( " $\"3n=12\"$
\n" ); document.write( " $\"n=4\"$
\n" ); document.write( "So, the integers are 4,5 and 6.
\n" ); document.write( "The difference is then,
\n" ); document.write( " $\"D=6-4=2\"$ \r
