Two sets of numbers are given below. In each set, performing certain mathematical operations on the first number yields the second number, and performing the same mathematical operations on the second number yields the third number, and so on. Which of the given options follows the same operations as those followed in the given sets? (Note: The operations should be performed on the whole numbers without breaking them down into their constituent digits. For example, consider the number 13. Operations such as adding/subtracting/multiplying etc. can be performed on 13. Breaking 13 into 1 and 3 and then performing mathematical operations on them is not allowed.) 19-25-50-62 47-53-106-118
