Mental Aerobics…

Posted By: Randy GageMarch 13, 2009

Yesterday we talked about developing new neural pathways in your brain.  So since today is a lazy Friday, it’s a good time to exercise your brain cells.  Here’s a mental challenge for you.  The first person to solve it gets the prestige, fame and adulation of the millions or readers of my blog!  Here’s your challenge:

Look at the pattern below and tell me what number should replace the question mark.

9 7 8 5
3 1 4 3
8 8 7 6
2 2 3 ?

Hit me with your best shot!

  1. Oops, when I posted my answer, I thought I was the first one sine no one left any comments. The internet is damn slow here, hmm.

    Greogry, congrats! I think we solved it :).

  2. 9785 - 3143 = 6642
    8876 - 3143 = 5733

    6642 - 5733 = 909

    8876 - 5733 - 909 = 2234

    So the last number is 4

    Everyone have an awesome weekend!

  3. Top to bottom logic
    AND side to side logic
    AND adding the 4 digits downwards
    AND adding the 4 digits sidways

    ALL call for a 4!

  4. Right - 4 comes up in many ways, including adding every two numbers to make a repeating pattern as such:

    16 13

    4 7

    16 13
    4 7

  5. It's 4 - the patterns all add up to the want of the 4. That was fun - even though I know it's a great way to collect my addy.

  6. 9 + 7 + 8 + 5 = 29
    + + + +
    3 + 1 + 4 + 3 = 11
    + + + +
    8 + 8 + 7 + 6 = 29
    + + + +
    2 + 2 + 3 + four = 11
    = = = =
    22 18 22 18

  7. Okay yes the answer is 4. You get it by dividing all the numbers into four squares or 2X2 blocks. Each block of four numbers equals 20. If you got this, you’re very bright! Congratulations to Gregory who listed it first.

  8. I think it is four (4) because the fisrt column the total is 22, the second is 18, the three is 22 .. so...the fourth column most be 18 also , so the ? is 4. But I think most be more than one relationship, .... y will still search y when i finded y tell yow!!!!
