225 : 18

256 : 19

196 : 17

169 : 14

- Each number-pair follows a specific pattern where the second number is derived using the first number.

- For option 1, 225 : 18: The square root of 225 is 15. Adding 3 gives 18.

- For option 2, 256 : 19: The square root of 256 is 16. Adding 3 gives 19.

- For option 3, 196 : 17: The square root of 196 is 14. Adding 3 gives 17.

- Option 4, 169 : 14: The square root of 169 is 13. Adding 3 should give 16, not 14.

- Therefore, 169 : 14 does not fit the pattern.

Option 4 is the odd one out.
