please answer the full question and show the math on how you got the present value of the retirement account to match with the pensions. I will dislike if the answer is incomplete

You are retiring with a pension plan that currently pays $45,000 a year. The pension plan is adjusted for inflation and thus you expect the pension to grow by 3% a year. The pension plan can be given upon your passing to your heirs who can do the same. Your friend brags that she has a retirement account with $750,000 which is way better than a pension. Is she correct? How big would a retirement account have to be before it represented more wealth than your pension? Please show your math, I will dislike if only the answer are shown
