cfa level 1 Equity investment question

Can anyone tell me how to calculate this?
Sry for the being stupid"" it is about dividend discount model questions.

Assume that a stock is expected to pay dividend at the end of year 1 and year 2 of 1.25 and 1.56 respectively. Dividend are expected to grow at a 5% rate thereafter. Assume cost of equity is 11%, what is the value if yhe stock?

頂一下:)

terminal value at t2=1.56(1.05)/(11%-5%), then discout it back to t0 +pv(d1)+pv(d2)
