Problem of the Week #4

Posted: March 11, 2013

The number 90 can be expressed as the sum of 3 consecutive whole numbers. That is, 90 = 29 + 30 + 31. The number 90 can also be written as the sum of 4 consecutive whole numbers. That is, 90 = 21 + 22 + 23 + 24. Express the number 220 as the sum of 5 consecutive whole numbers and then as the sum of 8 consecutive whole numbers.   Please remember: First and Last Name Class Problem of the Week # Answer done on a sheet of looseleaf (folded in fourths in order to fit into the ballot box) Show how you found your answer (answer only will not be eligible for draw) Put your answer in a summative phrase (sentence form) with a circle around it (makes it clearer for the judges) Make sure your work is neat (the winner's solution will be posted on the website)
