John and Marsha are in an argument about an investment which requires a series of six annual deposits.

If an investor decides to invest, he/she has to deposit $30,000 at the end of year 1, $30,000 at the end of year 2, $30,000 at the end of year 4, $30,000 at the end of year 5, $30,000 at the end of year 6 and $30,000 at the end of year 7. The deposited amounts grow at a rate of 5% p.a.

The argument is about the nature of the cash flow stream of the six deposits whether the cash flows are an annuity or a mixed stream. As per Johns opinion, the value of this investment at the end of year 7 will be $244,260.25 while Marsha thinks that the value of this investment at the end of year 7 will be $207,795.07

You are required to assist both in coming to a resolution of the argument by doing as follows:

i) As per your own understanding of the cash flow pattern of deposits presented above, compute the value of the investment at the end of year 7. Clearly highlight all computational steps.
