Given that, the dividend amount just paid=$2.2
The company is planning on increasing its annual dividend by 15 percent a year for the next 4 years. So, the dividend payments in the coming 4 years will be:
Year 1:$2.2*(1+15%)=$2.53

Year 2:$2.53*(1+15%)=$2.9095

Year 3:$2.9095*(1+15%)=$3.345925

Year 4:$3.345925*(1+15%)=$3.84781375

Terminal value=(Dividend in year 4)*(1+Growth rate)/(Required rate of return - Growth rate)

The growth rate will decrease to 5 percent per year after year 4.
Given that the required rate of return is 7.70 percent.
Terminal value=$3.84781375*(1+5%)/(7.7%-5%)
=$3.84781375*(1.05)/(2.7%)
=$3.84781375*38.88888889
=$149.6372014

Present value of the stock=(Dividend in year 1)/(1+required return)^1+(Dividend in year 2)/(1+required return)^2+(Dividend in year 3)/(1+required return)^3+(Dividend in year 4)/(1+required return)^4+Terminal value/(1+required return)^4
