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)
Answer & explanation
Correct answer: option 1
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
