Problem #5
The number 9 can be written as the sum of two consecutive positive
integers: 9 = 4 + 5. It can be written as the sum of at least two
consecutive positive integers in exactly two ways: 9 = 4 + 5 and 9 = 2 + 3
+ 4. Is there a positive integer that can be written as the sum of 2003
consecutive positive integers and can be written as the sum of at
least two consecutive positive integers in exactly 2003 ways?
What if 2003 is replaced by 2002?
