Recursive Formula--
It is the formula which is used to represent the nth term of a sequence in terms of (n-1)th term of the sequence.
Here we are given a table of values by:
n f(n)
1 4
2 20
3 100
i.e. when n=1 we have:

Answer: 379.94
The diameter is given as 22 inches, the radius would be 2/2 = 11 inches.
Area = 3.14 * 11^2
Area = 3.14 * 121
Area = 379.94 square inches.
Y = kx
Y is the total cost
The number of dvds is x
The cost of each one ($12) is k
y = $12x
Or instead of Y you can but T for total cost
t = $12x
