Let's see the pattern by dividing them in parts: Part 1 - 7 + 5 = 12 12 + 9 = 21 Part 2- 5 + 11 = 16 16 + 12 = 28 We see here that in every part, the difference between the first and second numbers is rising by 6. Also, the difference between the second and third numbers is increasing by 6. So by following the same pattern , we can find the missing number which is: 12 + 17 = 29 Hence, the missing number is 29.
Question : Directions: Three of the following number pairs are alike in some manner and one is different. Select the odd number pair. (NOTE: The second number in the given number pairs is formed by performing a certain operation on the first number. The same operation is followed in all the number pairs except one. Find that odd number pair.)
Option 1: 297 : 33
Option 2: 189 : 21
Option 3: 100 : 12
Option 4: 63 : 7
