In the following question pairs are given. In each pair the number on left side of (-) is related to the number of the right side of (-) with some Logic/Rule/Relation. Three pairs are similar on basis of same Logic/Rule/Relation. Select the odd one out from the given alternatives. (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 2
The logic followed here is :
(Ist term × 2) - 2 = IInd term
16 - 30 = (16 × 2) - 2 = 30
44 - 84 = (44 × 2) - 4 = 84 ODD
14 - 26 = (14 × 2) - 2 = 26
18 - 34 = (18 × 2) - 2 = 34
