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)

14 - 193

The logic followed here is :

(Ist term)² - 5  = IInd Term

14 - 193 = 14² - 3 = 193 ODD

15 - 220 = 15² - 5 = 220

16 - 251 = 16² - 5 =251

17 - 284 = 17² - 5 = 284
