Answer 1

What are your options?

Answer 2

If you divide 4158/1663.2, you get 2.5 and if you use 2.5 to divide each time, it gives you the same numbers that are given in the question, so it seems like the answer would be dividing by 2.5 (if that is an option)

Answer 3

You could also describe it as a geometric function with a common ratio of 2/5.
