The logic used here is: 1st number × (1st number - 2) = 2nd number Option 1: 12: 120 12 × (12 - 2) = 12 × 10 = 120 This follows the logic. Option 2: 13: 143 13 × (13 - 2) = 13 × 11 = 143 This follows the logic. Option 3: 18: 288 18 × (18 - 2) = 18 × 16 = 288 This follows the logic. Option 4: 11: 111 11 × (11 - 2) = 11 × 9 = 99 This does not follow the logic. Hence, option 4 is the odd one out. |
