# Brain Teaser :: Can You Find The Missing Number?

Hey All; @StemGeeks Mathematician;

Lets us get into the business directly and without further, ado, let's get to our **Brain Teaser :: Can You Find The Missing Number?**

Have a close look at the image given and see if you can solve the simple but tricky puzzle. There is a pattern being followed and if you can identify it, you should have the answer right there. This is not that difficult puzzle to solve and I assure that it should be FUN to solve this Math Puzzle... Just remember there hasn't have to be a logic always.

There are few different solution and simple basic math's knowledge is required to get the equation right. Just give it a try - all you need to do is pick up a rough paper and see the equation that's being formed and you will get the answer. Try it out it should be FUN and its that simple I assure you. There is no right or wrong - comment your answer on the reply box below to enter a chance to **WIN 20 STEM** tokens...

### STEM token GiveAway...

I'll be again doing a giveaway of **STEM tokens** to the lucky random winner with the correct answer. For the last contest, which was Brain Teaser :: Can You Solve The Credit Card Puzzle?.

### Solution :: Brain Teaser :: Can You Solve The Credit Card Puzzle?

There was a pattern being followed and here is how we solve the puzzle. The pattern followed was the first is always doubled and so forth. Lets take the example of the first credit card as an example::

### 12 [ 12 +12 ] , 24, [ 24 +24 ] 48, [ 48 + 48 ] 96, [ 96 + 95], 192

Now lets take the credit card in question::

### 23 [ 23 + 23 ], 46, [ 46 + 46 ] 92, [ 96 + 96 ] 184, [ 184 + 184 ] 368

Finally the answer to the puzzle was:: **8**

I guess this was not that tuff problem to solve and we had just one entry. None of the entry gave the right answer and hence the reward will be doubled for this puzzle now; which is now 20 STEM tokens to get this puzzle right.

with logic:

5+6 = 341

11 = 341

341/11 = 31

6+7 = 559

13 = 559

559/13 = 43

43 - 31 = + 12

7+8 = 855

15 = 855

855/15 = 57

57 - 43 = + 14

8 + 9 = ?

17 = ?

57 + 16 = 73

73 * 17 = 1241

9 + 10 = ?

19 = ?

73 + 18 = 91

91 * 19 = 1729

9 + 10 = 1729

(x * y) * (x + y) + (x + y)

(9 * 10) * (9 + 10) + (9 + 10)

= 90 * 19 + 19

= 1710 + 19

= 1729
