Below are given two sets of numbers. In each set, 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 operations as the sets given in the question? (Note - a two/three-digit number cannot be broken into separate digits for the operations; for example, if 10 comes after 37, the operation cannot be 3+7 because a two-digit number cannot be broken into separate digits.) 11 – 22 – 44 – 88 ; 13 – 26 – 52 – 104
