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,-28 -42)

The logic followed here is :

Ist number × 2 = second number , Ist number × 4 = Third number

( 16 -32 - 64)

(18 -36 - 72)

(12 -24 - 48)

Except option 1

14  ,  14 × 2 , 14 × 3

  14 , 28 ,  42
