Suppose an initial deposit of D dollars into a savings account yields a fixed percentage r per year.

The following withdrawal scheme is used:

After the first year the account holder withdraws W dollars out of the account. Following the second year, the account holder withdraws V dollars out of the account. The account holder continues to withdraw W or V dollars each year in an alternating fashion. (Refer to your notes for the partial sum of a geometric series and compare this exercise with Worksheet 3.)

Find an equation that shows the value of the account after N years. (Assume N is odd. This will affect indexing. This assumption will simplify your answer.)

Here, record the part of your expression that involves the term D.

Here, record the part of your expression that involves the term W.

Here, record the part of your expression that involves the term V.
