### Solution :: Brain Teaser :: Can You Complete The Circle #Z?

###### Pattern being followed was:: the difference of numbers in upper half of the circle and then multiply by the difference from the number from the second half circle i.e.::

Image X:: (8 - 4) x (3 + 2) = 20

Image Y:: (10 – 7) x (3 + 1) = 12

Image Z:: (9 – 3) x (1 + 2) = ?? = 18

Finally the answer to the puzzle was:: **18**

It is a continue Addison of each new number let the answer be X . So now I am looking for X. How to fine X.

X + 1= 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

So now to fine X you make X to stand alone, collect like terms

X = 1 - 1

X = 0

So therefore the correct answer is 0

Thanks
