    6 completes the sequence in the yellow ovals (4..5..6) as well as the red ovals (72/18 = 4 95/19 = 5 84/14 = ?)

    i think one answer is 6. Explanation:
    1) In the first ellipse 72/18= 4
    2)In the second 95/19= 5
    3) So in the third 84/14= 6

    the top two numbers divided by the bottom two numbes, is the overall top number, so 6 would be the answer.

    A B
    C D
    # = (D – A +C) * B
    1. (8 – 7 + 1) * 2 = 4
    2. (9 – 9 + 1) * 5 = 5
    3. (4 – 8 + 1) * 4 = -12

    -12


  6. Ray | Guest

    How about -12?


    (((8-7)+1)*2) = 4
    (((9-9)+1)*5) = 5
    (((4-8)+1)*4) = -12


  7. Rupert Parson | Guest

    ..X..
    A…B
    C…D


    X = ((D-A)+C)*B


    4 = ((8-7)+1)*2
    5 = ((9-9)+1)*5
    -12 = ((4-8)+1)*4


  8. Shawn | Guest

    The answer could be -12.


    Formula is:


    (Lower Right – Upper Left + Lower Left) * Upper Right


    First ovoid = (8 – 7 + 1) * 2 = 2 * 2 = 4
    Second ovoid = (9 – 9 + 1) * 5 = 1 * 5 = 5
    Third ovoid = (4 – 8 + 1) * 4 = -3 * 4 = -12

    6

    The missing number is 6. These are division problems, 72/18 = 4, 95/19 = 5, and 84/14 = 6.


  11. michael kim | Guest

    6


  12. Milo Zachary | Guest

    6

    Take each of the top and bottom two red numbers as two digits and divide the bottom number by the top, so:


    72 / 18 = 4
    95 / 19 = 5
    84 / 14 = 6


  14. Rasool | Guest

    The top two numbers divide by two bottom 72/18=4, 95/19=5, 84/14=6.
    So the answer is 6.

    6 is the answer we originally had in mind, but as Joe, Rupert, Shawn & Ray point out, -12 works too!


  16. MK | Guest

    Take the ones digit of the product of the top left and right red numbers as the yellow number and then the answer is w


    7*2 = 14 —— 4
    9*5 = 45 —— 5
    8*4 = 32 —— 2


  17. Smartesthumanalive | Profile

    Its 7
    EX:
    (7-1+8) = 2 *2 = 4
    (9-1+9) = 1 *5 = 5
    (8-1-4) = 3 *4 = 12


  18. Jerrud Edwin | Profile

    Yea just goes to show that many can get a wrong answer on an IQ test when in fact they came to another correct answer because they thought a little deeper. Too bad my math skills stink ;-)


  19. san2uu | Profile

    another answer: 0 also..
    explanation:
    take lower semi circle numbers;
    8-1=7 7-3=4
    9-1=8 8-3=5
    ????answer????
    4-1=3 3-3=0
    :)
