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!
