Consecutive even integers: they are not necessarily consecutive, but they are consecutive if you only look at the even numbers. 10, -9 ,-8 ,-7 -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Consecutive odd integers: they are not necessarily consecutive, but they are consecutive if you only look at the odd numbers. 10, -9, -8, -7 -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The sum of four consecutive integers is 762.
