#### Puzzle of the Day

These puzzles are also printed in Eight days a week, a booklet published by the Association of Teachers of Mathematics.

The five consecutive numbers 1, 2, 3, 4, 5 added together come to 15. The three consecutive numbers 4, 5 and 6 also add to 15. There is one other way to add consecutive numbers to make 15. Can you find other numbers which can be made by adding several different sets of consecutive numbers?

Answer: No Limit. e.g. 45 is 22+23, 14+15+16, 7+8+9+10+11, 5+6+7+8+9+10
