Step-by-step explanation:
Given
Round 0 1 2 3
Points 25 75 225 675
Required
Determine the equation
Let n = rounds and p = points.
So, we have:



The above shows a geometric progression.
So, we solve using

In 
n = 0 and p = 25
Substitute these values in 




In 
n = 1 and p = 75
Substitute these values in 


Substitute 25 for a

Make b the subject


So, we have:
and 
The equation
becomes
