Problem of the week (check the scoring guide) The problem of the week is due next Monday. Students are to use diagrams, charts, and tables as needed. Explain the process used to solve the problem. Be neat.
The following problem was suggested by Dr Ron Knott while he was visiting the Math Forum from his home in Surrey, United Kingdom.We need to start be defining a few terms that we will want to use. A run of numbers is a collection of whole numbers with no gaps in it, such as 2, 3 and 4; but not 5, 6, 8, 9 because 7 is missing and neither is 2, 3, 3 a run because 3 is repeated. Practically all numbers can be written as a SUM OF A RUN (we will not allow a run to start at 0). For example, 9 = 2 + 3 + 4, 10 = 1 + 2 + 3 + 4, 11 = 5 + 6 and we will call them RUNSUMS but there is no run with a sum of 4 or 8 (so 4 and 8 have no runsum). The questions you will need to explore:
By spotting the pattern tell me the smallest number which is a sum of a run of ONE HUNDRED consecutive numbers. Here is the hard part, I want to know HOW you know.
- What is the SMALLEST number that is a sum of a run of THREE numbers?
- What is the SMALLEST number that is a sum of a run of FOUR numbers?
- What is the SMALLEST number that is a sum of a run of FIVE numbers?
Bonus: What is the SMALLEST number that is a sum of a run of "n" numbers?
