When we count consecutive numbers, we are really adding 1 to each number to get to the next: 1,2,3,4,...n,n+1
\n" ); document.write( "\"Sum\" means +
\n" ); document.write( "(first number)+(second number)=69
\n" ); document.write( "Let:
\n" ); document.write( "first number = n
\n" ); document.write( "second number = n+1
\n" ); document.write( " $\"n%2B%28n%2B1%29=69\"$
\n" ); document.write( " $\"2n%2B1=69\"$
\n" ); document.write( " $\"2n%2B1-1=69-1\"$
\n" ); document.write( " $\"2n=68\"$
\n" ); document.write( " $\"2n%2F2=68%2F2\"$
\n" ); document.write( " $\"n=34\"$
\n" ); document.write( "first number = n = $\"highlight%2834%29\"$
\n" ); document.write( "second number = n+1=34+1= $\"highlight%2835%29\"$ \r
\n" ); document.write( "\n" ); document.write( "
Remember for word problems to always do a sanity check. Are 34 and 35 consecutive? YES Does 34+35=69? YES So unless something weird happened we are likely right. :)
