The formula gives the MV is the first dividend is in 1 years time.
Here the first growing dividend is in 3 years time and so the answer needs discounting.
Also, there is a dividend on 0.25 in 2 years time, so this needs discounting also and adding on to get the full MV.
If you watch my free lectures working through Chapter 15 of our free lecture notes I explain all this. Especially the lecture working through Example 7 in the chapter.
