Ok, so if you have x dollars in your account and it grows at 4% annually, then in 15 years it will be

x * (1 + .04) ^15

you want this to equal 4000, so solve that equation with logs

nope

you're looking for the present value of annuities

given as


where
C = Cash flow per period
i = Interest rate
n = Number of payments

/e: this assumes that the first withdrawal happens 1 year after the bank account has this value.
so at time 0 the account must have the PV you find with the equation in order to make the first payout at time 1, which is one year later
