2.26,127

3.50,343

4.82,730

Dear Student!

Here is the answer to your question.

The rules followed by the pairs of numbers is explained below. 

1) 10, 28

10 = 32 + 1

28 = 33 + 1

 

2) 26, 127

26 = 52 + 1

127 = 53 + 2

 

3) 50, 343

50 = 72 + 1

343 = 73

 

4) 82, 730

82 = 92 + 1

730 = 93 + 1

 

It can be observed that in the options 1, 2 and 4, no number is perfect square or perfect cube of any other number.

In option 3, the number 343 is cube of 7 which is different from the rule followed by the other three pairs of numbers. Thus, option 3 has different type of pair of numbers.

Cheers!
