DF is half of AC, so DF=25
In this exercise we have to use the knowledge of geometric progression to find three specific numbers, in this way we can say that these numbers correspond to;
Then using the formula of the geometric progression we find that:
now, the differences between the terms must be the same:
and now, when we increase the third term by 9,so we have:
Now we use that identity in the first equation :
The general solution for a quadratic equation is
We have that:
so, put the numbers in the formula we find:
