Answer:
5x^7
Step-by-step explanation:
Use area formula (length x width)
42 x 25.5 = 1,071
Divide by total cost of wall paper
1,071/771.25 = $1.38 per square foot
18x = 162
18 eggs per x cartons is 162
x = 9 cartons
The recursive formula is
.
<h3>What is Arithmetic Progression?</h3>
A set of numbers is an arithmetic progression (AP) or an arithmetic sequence such that the difference between successive words is unchanged.
Given:
A(n)=(-1)+(n-1)(-5)
A(n) = -1 - 5n + 5
A(n) = 4-5n
n=1
A(1)= 4-5= -1
n=2,
A(2) = -6
n=3
A(3)= -11
Hence, the recursive formula is
.
