Question 8.

Question 9.

A series of numbers can be generated from a single starting number by repeating a single operation.

2For example, with the operation shown, the starting number X = 4 generates the number 12, as this is equal to 4 – 4. The 2number 12 then generates the next number, 132, as this is equal to 12 – 12, and so on.

Which of the following starting numbers, when used with this operation, will generate a series of numbers that continually increases?

(A) –2

(B) –1

(C) 0

(D) 2
