    Consecutive Problem?

    The sum of 4 consecutive integers is -38. What are the numbers? Write & solve an equation.

    Can someone just help me with the equation? I'd appreciate it :]

    Solve x + (x + 1) + (x + 2) + (x + 3) = -38 for x.

    If n is an integer then

    n+(n+1)+(n+2)+(n+3)=-38 \iff 4n+6=-38 \iff 4n=-44 \iff n =-11

    So we get

    -11,-10,-9,-8

    Edit too slow
