A firm is expected to pay a dividend of $1.00 next year. Dividends are expected to grow by 20% the year after that. For the next two years dividends will grow by 15% each year. Thereafter the dividends are only expected to grow by 5% each year. The appropriate required rate of return for this investment is 15%? What is the fair price of the stock today

My question is, how do you get the numbers: 1.2, 1.38, 1,587?
