the sum of three consective even integers is negative 300
You square the number of integers you are looking for, in this case; 300. So, 300 squared = 300 x 300 = 90,000. Thus, the sum of the first 300 odd numbers is 90,000.
The sum of the integers from 1 through 300 is 44,850.
The sum of two even numbers is always an even number.
The sum of two even numbers is always an even number.
Go through each of the numbers, and count how many of them are odd. If you count an odd number of them, then their sum is odd. If you count an even number of them, then their sum is even.
