You open a bank account, making a deposit of $500 now and deposits of $1,000 every other year. What is the total balance at the end of 10 years from now if your deposits earn 4% interest compounded annually?

(This means there is an initial deposit of $500 and then $1,000 deposits skipping one year. That is, at the end of the first year, there is no deposit; at the end of the second year, there is a $1,000 deposit; at the end of the third year there is no deposit; and so on.)
