Four number pairs have been given, out of which three

Q: Answer-Four number pairs have been given, out of which three are alike in some manner and one is different....

The logic used here is The difference between the second number and the first number in each pair should be 111. Option 1 123, 234 234 - 123 111. This follows the logic. Option 2 345, 456 456 - 345 111. This follows the logic. Option 3 567, 729 729 - 567 162. This does not follow the logic. Option 4 678, 789 789 - 678 111. This follow the logic. Hence, option 3 is the odd one out.
