relationship between future value and present value: mixed stream The table below shows a mixed cash flow stream except that the cash flow for year 3 is missing

Year 1 $10,000, Year 2 5,000, Year 4 20,000, Year 5 3,000

Suppose that somehow you know that the present value of the entire stream is $32, 911.03 and that the discount rate is 4%. What is the missing cash flow in year 3?
