### Number Series Math Riddle Solution

Hopefully, you enjoyed solving this number series math riddle and did it within the given time limit. Now, it’s time to check the answer. The missing number in the third central circle is 100.

Sounds unexpected, right?

Don’t be surprised. Many people failed to find the answer.

Refer to the below method to learn how to crack this number series riddle.

The numbers in the circle appear random at first, but if you think hard and perform the basic arithmetic operations: addition, subtraction, multiplication and subtraction, you’ll notice a pattern.

Here are the steps to reach the solution.

- Observe the first circle and pair the opposites 5 & 9, and 8 & 6.

- Multiply both pairs

You get (5 x 9) = 45 & (8 x 6) = 48

- Now calculate the difference and find its square

48 - 45 = 3

- Now squaring it,

32 = 9

Similarly for the second circle:

(11 x 2) = 22 & (5 x 3) = 15

=> 22 - 15 = 7

=> 72 = 49

And finally coming to Circle Three:

(12 x 9) = 108 & (7 x 14) = 98

=> 60 - 54 = 10

=> 102 = 100
