Answer:
the interest rate is missing, so I looked for similar questions and found that the semiannual interest rate is 3%.
first of all, we must determine the amount of money that we need to have in our account in order to be able to withdraw $25,000 in 10 years.
You will start making your semiannual deposits today and they will end in exactly 2 years, so we need to find out the present value of the $25,000 in two years:
PV = $25,000 / (1 + 3%)¹⁶ = $15,579.17
that is now the future value of our annuity due:
FV = semiannual deposit x FV annuity due factor (3%, 5 periods)
$15,579.17 = semiannual deposit x 5.46841
semiannual deposit = $15,579.17 / 5.46841 = $2,848.94
