    1 8 1 4 7 0 7 0 ?

    Answer: 3
    Why?
    Because :

    – Level 1 -||- Level 2—
    1 -> 8 : +7 || +7 -> -7 : -14
    8 -> 1 : -7 || -7 -> +3 : +10
    1 -> 4 : +3 || +3 -> +3 : 0
    4 -> 7 : +3 || +3 -> -7 : -10
    7 -> 0 : -7 || -7 -> +7 : +14
    0 -> 7 : +7 || +7 -> -7 : -14
    7 -> 0 : -7 || -7 -> y : z
    0 -> x : y |||

    -14 +10 0 -10 +14 -14 z
    By following this trail, take the result that
    z = +10
    y = (-7) + z = +3
    x = 0 + y = +3
