Number Series Math Riddle Solution
Hopefully, you had fun solving this number series riddle and did it under the time limit. Now, it’s time to check the solution. The missing number in the central circle is 72.
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 seem completely random at first glance, but if you perform the basic arithmetic operations: addition, subtraction, multiplication and subtraction, you’ll notice the pattern.
Here are the steps to reach the solution.
- Observe the first circle and pair the opposites 7 & 6, and 8 & 4.
- Add the first pair and square the result. You get (7 + 6)2 = 132 = 169
- Now repeat the same process for the second pair. You get (8 + 4)2 = 122 = 144
- Now subtract the difference between the squares of the sums of the opposite pairs on the circles.
- 169 - 144 = 25
Similarly for the second circle:
(11 + 3)2 = 142 = 196
(9 + 6)2 = 152 = 225
225 - 196 = 29.
And finally coming to Circle Three:
= (10 + 1)2 - (5 + 2)2
= 112 - 72
= 121 - 49
= 72
There’s your answer.
