Below are given two sets of numbers. In each set of numbers, performing a certain mathematical operation on the first number gives the second number. Similarly, performing a certain mathematical operation on the second number gives the third number, and so on. Which of the given options follows the same set of operations as used in the given sets? (Note: without breaking numbers into their constituent digits, operations must be performed on whole numbers only. For example, take 13 - operations on 13, such as adding/subtracting/multiplying to 13, can be performed. Breaking 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 4 – 16 – 26 – 52; 7 – 49 – 59 – 118
