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 4
Except option 4
Same logic is followed that add 4 in previous number
(16-20-24) = 16 , 16 + 4 , 20 + 4
(23-27-31) = 23 , 23 + 4 , 27 + 4
(11-15-19) = 11 , 11 +4 , 15 + 4
(12-14-18) = 12 , 12 +2 , 14 + 4 which is odd
