The second number in the given number-pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) is/are followed in all the number-pairs except one. Find that odd number-pair. 9 : 1458, 3 : 54, 5 : 685, 5 : 250
5 : 685
The operation followed in the series involves multiplying the number by a certain factor. However, in the pair (5 : 685), the relationship is different from the others. The correct odd number-pair is (5 : 685), as it does not follow the same multiplication pattern as the other pairs.
