What is next in this series 45, 22.5, 33.75, 84.37, 295.31, …?

Answer 1

45 * 0.5 = 22.5

22.5 * 1.5 = 33.75

33.75 * 2.5 = 84.375

84.375 * 3.5 = 295.3125

295.3125 * 4.5 = 1328.90625

Whether they were truncating to 2 decimal places or rounding down would determine if their final answer is 1328.90 or 1328.91.
