Answer:
I'd say perimeters most likely
Step-by-step explanation:
Parameter because you add the outsides
Part A)
Part B)
1. 4
2. 16
3. 4/3
4. 64/3
add 4 each time
the nth term is a_n or f(n)
the next term after that is a_{n+1} or f(n+1)
so each term is 4 more than previous
basically
a_{n+1}=4+a_n or
f(n+1)=4+f(n)
same thing
