    To solve this equation, we have to set up an equation.

    Since they are three consecutive numbers, x3 = x2 + 2, x2 = x + 2

    x + (x + 2) + (x + 4) = 2040

    3x + 6 = 2040

    x + 2 = 680

    x = 678

    The three consecutive even numbers are 678, 680, 682

    A quick way to find the median number of the integer list is to divide the sum by the N amount of consecutive integers.

    Ex. 2040/3 = 680. Since there are only 3 numbers, we just subtract two and add two (in the case that it is even consecutive numbers) and get 678, 680, 682
