Most natural numbers can be expressed as a sum of two or ore consecutive positive intergers. Find all natural numbers between 1,000 and 10,000 which cannot be expressed as a sum of tow or more consecutive positive intergers.
Even numbers would not be expressed in terms of two consecutive positive integers. How many "more" than two do you need to consider?
I hope this helps a little. Thanks for asking.
