   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

   How about -12?

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

   ..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

   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

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

    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!

    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

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

    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
