Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 - Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

16 - 263

THE LOGIC FOLLOWED HERE IS :

IST NUMBER² + 5 = IIND NUMBER

AS

18 - 329

18² + 5 = 324 + 5 = 329

16 - 263

16² + 5 = 256 + 5 = 261 ≠ 263 (ODD)

14 - 201

14² + 5 = 196 + 5 = 201

12 - 149

12² + 5 = 144 + 5 = 149
