Do the numbers in the perimeter row form an arithmetic sequence? If so, what is the common difference, and what is the recursive formula for the perimeter of a square of side n(the nth perimeter) using the first number(perimeter) in the pattern?

Answer:
Step-by-step explanation:
Let the perimeter of the square with length of n be Pā.
According to given table we have:
We can put this as a sequence:
Common difference is:
The recursive formula for this sequence is:
