(a) To calculate the equivalent value at the end of the second year (V2) of that part of the series, we should use the following linear gradient factor: with the value of: and the following uniform series factor: with the value of (b) The equivalent value at the end of the second year of that part of the series (V2) is $ (c) The equivalent Present Value of that part of the series (P) is $ (d) The equivalent Present Value of the whole series of six cash flows illustrated in the cash flow diagram on the left-hand side (Ps) is s (e) The unknown value that satisfies the equivalence (X) is $
