Write a recursive expression

When n = 1


When n = 2

can be rewritten as

Substitute 3 for f(1)

Express 1 as 2 - 1
----- (1)
When n = 3

can be rewritten as

Substitute 8 for f(2)

Express 2 as 3 - 1
------ (2)
Write out (1) and (2)


Replace 2 and 3 with n in both cases; This gives

Hence;
The recursive is

Answer:
<u>One Rectangular Pan</u>
Step-by-step explanation:
Part C cannot be answered since the dimensions of the pool are not given. Please check the question.
The cake pans may be compared by calculating the volume of each shape:
Rectangular pan: Volume = Length x Width x Height
Volume Rectangle = (13")*(9")*(2") = <u>234 in^3</u>
Round pan: Volume = 
Volume Round = (3.14)*(4")^2(2") = 100.5 in^3
Two round pans will hold 2*(100.5 in^3) or 201 in^3 of batter
One rectangular pan holds 234 in^3.
Go with the rectangular pan if you want more cake.
