Select the option in which the numbers are not related

Solution

The logic followed here is: The 1st number is multiplied by 2 to get the 2nd number. The 2nd number is multiplied by 4 to get the 3rd number. In (9, 18, 72) → (2 X 9) = 18, (4 X 18) = 72 In option 'a': (14, 28, 112) → (2 X 14) = 28, (4 X 28) = 112 In option 'b': (11 22, 88) → (2 X 11) = 22, (4 X 22) = 88 In option 'c': (18, 36, 144) → (2 X 18) = 36, (4 X 36) = 144 In option 'd': (13, 26, 66) → (2 X 13) = 26, (4 X 26) = 104 ≠ 106
