Excel does not have a function for the sum of the future values for a set of uneven payments. Therefore,
we must find this FV by some other method. Probably the easiest procedure is to simply compound each
payment, then sum them, as is done below. Note that since the payments are received at the end of each
year, the first payment is compounded for 2 years, the second for 1 year, and the third for 0 years.
	Year	Payment	x	(1 + I )^(N t)	=	FV
	1	100		1.1664		116.64
	2	200		1.0800		216.00
	3	400		1.0000		400.00
					Sum of FV's =	732.64		You just need to sum, I've calculated compounding factors and FVs for you above
An alternative procedure for finding the FV would be to find the PV of the series using the NPV function, then compound that amount for 3 years at 8%, as is done below:
	PV =????
	FV of PV =?????
