Question

Find the odd man out, among the given number groups. 92432, 48422, 67626, 78428

Answer 1

Given,

The given numbers are = 92432, 48422, 67626, 78428

To find,

The odd number in the given sequence.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

If we observe the given numbers then we will get that in the three out of four given numbers, the square of the last two digits is exactly equal to the first three digits in the proper sequence.

1. 48422 » (22)² = 482
2. 67626 » (26)² = 676
3. 78428 » (28)² = 784

But, the first number doesn't match the above mentioned criteria.

92432 » (32)² = 1024 ≠ 924

Hence, the odd number is 92432
