Call the first odd integer ... x \n" ); document.write( ". \n" ); document.write( "then the next odd integer is x + 2 \n" ); document.write( ". \n" ); document.write( "the third consecutive odd integer is x + 4 \n" ); document.write( ". \n" ); document.write( "the fourth consecutive odd integer is x + 6 \n" ); document.write( ". \n" ); document.write( "Note that these show that the difference between consecutive odd integers is 2 ... think in \n" ); document.write( "terms of 3, 5, 7, and 9 being consecutive odd integers and note that each is 2 away from \n" ); document.write( "its predecessor. \n" ); document.write( ". \n" ); document.write( "If you add our 4 consecutive odd integers you get: \n" ); document.write( ". \n" ); document.write( "x + (x + 2) + (x + 4) + (x + 6) = 4x + 12 \n" ); document.write( ". \n" ); document.write( "but you are told that this sum is 196. So set the sum equal to 196 and write it in the form \n" ); document.write( "of an equation to get: \n" ); document.write( ". \n" ); document.write( "4x + 12 = 196 \n" ); document.write( ". \n" ); document.write( "Get rid of the 12 on the left side by subtracting 12 from both sides to convert the equation to: \n" ); document.write( ". \n" ); document.write( "4x = 196 - 12 = 184 \n" ); document.write( ". \n" ); document.write( "Then solve for x by dividing both sides by 4 to get: \n" ); document.write( ". \n" ); document.write( "x = 184/4 = 46 \n" ); document.write( ". \n" ); document.write( "What does this tell us? This cannot be an answer because the first number in the series is \n" ); document.write( "an even number. Add up the 4 consecutive even integers ... that is add up 46 + 48 + 50 + 52 \n" ); document.write( "and you get 196 as the sum. \n" ); document.write( ". \n" ); document.write( "Try nearby odd numbers ... the sum of 45 + 47 + 49 + 51 equals 192. This is too small so the \n" ); document.write( "series has to be \"upped.\" Find the sum of 47 + 49 + 51 + 53 = 200. This is too big. So there \n" ); document.write( "is no series of four consecutive odd numbers that will add to 196. \n" ); document.write( ". \n" ); document.write( "The conclusion is that this problem has no solution. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand the problem and how to work on it. \n" ); document.write( ". \n" ); document.write( " |
