Determine the recursive formula
The given sequence shows arithmetic progression (AP).
First, we calculate the common difference (d):
The recursive formula of an AP is determined using:
where
Substitute 3 for d

Answer:
The total area between the squares is of 24 units squared.
Step-by-step explanation:
Area of a square:
The area of a square of side length l is given by:
Area between figures:
The area between two figures is the area of the larger figure subtracted by the area of the smaller figure.
Larger square:
Square with side of length 7. So
Smaller square:
Square with side of length 5. So
What is the total area between the squares?
The total area between the squares is of 24 units squared.
