Answer:
x = 45
Step-by-step explanation:
Given
 = 9
 = 9
Multiply both sides by 5
x = 5 × 9 = 45
 
        
                    
             
        
        
        
The given sequence is
a₁, a₂, ..., 

Because the given sequence is an arithmetic progression (AP), the equation satisfied is

where
d =  the common difference.
The common difference may be determined as
d = a₂ - a₁
The common difference is the difference between successive terms, therefore
d = a₃ - a₂ = a₄ - a₃, and so on..
The sum of the first n terms is

Example:
For the arithmetic sequence
1,3,5, ..., 
the common difference is d= 3 - 1 = 2.
The n-th term is

For example, the 10-term is
a₁₀ = 1 + (10-1)*2 = 19
Th sum of th first 10 terms is
S₁₀ = (10/2)*(1 + 19) = 100

What is the area of rectangle?
The area of a rectangle is the product of its length and width. That is,       A = l x w where l is the length and w is the width of the rectangle. 
Here, Required Paint = 
                                    = 5 X 37  - 36
                                    = 185 - 36
                                    = 149
                                    = 1.49 gallons
Thus, Randy needs to purchase 1.49 Gallons of paint to cover 100 sq. feet wall.
