Question

Two sets of numbers are given below. In each set of numbers, certain mathematical operation(s) on the first number result(s) in the second number. Similarly, certain mathematical operation(s) on the second number result(s) in the third number and so on. Which of the given options follows the same set of operations as in the given sets?

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
6 – 16 – 23 – 32; 7 – 19 – 26 – 35

The correct answer is

12 – 34 – 41 – 50

Let's examine the given sets of numbers and identify the operations involved:

Set 1: 6 – 16 – 23 – 32
Set 2: 7 – 19 – 26 – 35

First, we need to identify the operations applied from one number to the next:

  • In Set 1, from 6 to 16: Add 10.
  • In Set 1, from 16 to 23: Add 7.
  • In Set 1, from 23 to 32: Add 9.

Now, let's verify if the same pattern is applied to Set 2:

  • In Set 2, from 7 to 19: Add 12.
  • In Set 2, from 19 to 26: Add 7.
  • In Set 2, from 26 to 35: Add 9.

Now, we need to find an option that follows the same pattern. Let's analyze the given options:

  • Option 1: 12 – 34 – 41 – 50
  • Option 2: 11 – 31 – 38 – 29
  • Option 3: 4 – 14 – 21 – 30
  • Option 4: 8 – 22 – 15 – 24

From the calculations and observations, the option that follows a similar pattern to the given sets "Add 10, Add 7, Add 9" is:

  • Option 1: 12 – 34 – 41 – 50

Hence, the correct answer is Option 1: 12 – 34 – 41 – 50.
