You have a strict linear gradient series, with the amount of +537 Euros that is starting with the first cash flow in the gradient in the second year and continuing on until year seven. There is also a single cash flow of +827 Euros at the end of the first year. Your interest rate is 9.5% per year compounded semiannually. What is the Annual Equivalent Worth of that series of cash flows (over seven years and given in Euros)? Note 1: Please enter your answer to two decimal places, as a number only. Note 2: If using the interest factor method, apply the value of the factor as presented in the table or spreadsheet (with all four decimal places)
