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.

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 FIND the Missing Number?.

### Solution :: Brain Teaser :: Can You FIND the Missing Number?

###### Here we had to apply the Formula -->

#### x + y * 2nd Number’s Unit Place Digit; lets take the example for each rows

Row 1 => x + y * 2nd Number’s Unit Place Digit = 12 + 13 * 3 = 25 * 5 = 75

Row 2 => x + y * 2nd Number’s Unit Place Digit = 15 + 16 * 6 = 31 * 6 = 186

- Row 3 => x + y * 2nd Number’s Unit Place Digit = 11 + 12 * 2 = 23 * 2 = 46

Now lets take the last row in question which is :: 14 + 15 = ?

- Row 4 => x + y * 2nd Number’s Unit Place Digit = 14 + 15 * 5 = 29 * 5 = 145

Finally the answer to the puzzle was:: **145**

I guess this was a tuff problem to solve and we had just six entries for the same. And all of the entries provided the right the right answer.. I am going to use a random picker tool to pick a random winner.

Congratulations @rishi2184 - You WIN yourself 10 STEM tokens each. You should be having the rewards in your STEM Wallet Soon.
