Two sets of numbers are given below. In each set, a certain mathematical operation on the first number results in the second number, on the second results in the third, and so on. Which option follows the same set of operations? (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into digits.) 2 - 8 - 32 - 160 3 - 27 - 108 - 540
