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

###### Pattern being followed was:: sum the total of each rows to see the pattern being made i.e. ::

- First Row Adding Up - 7 + 3 + 4 + 1 = 15
- Second Row Adding Up - 5 + 6 + 3 + 3 = 17
- Third Row Adding Up - 6 + 3 + 9 + 1 = 19

The final row in question:: if you see every rows last number is an increment of 2; therefore for the last row in question we have::

Final Row :: 4 + 8 + 2 + ? = 21

4 + 8 + 2 + 7 = 21

Finally the answer to the puzzle was:: **7**
