I need help with finding the N within a present value of annuity problem

Ok so here’s the question:
Your mother opens a bank account in your name when you were born (time = 0). She deposits $5,000 in that account every year. The first deposit was at time = 0 (on the day you were born) and the last deposit was time = 17 on (the day you turned 17). If the interest rate is 4%, what is the present value of all deposits on the day you were born (time = 0)?

So Im guessing you need to use the “payments made at the beginning” of each compound period formula. Im just confused if t=0 counts as another time. So T=17 or 18?

Draw a timeline.

How many deposits will she make?
