Step-by-step explanation:
 
        
             
        
        
        
Solution:
Given:
A table representing an exponential function.
The x-values represent the terms, while the y-values represent the numbers.
The common ratio is gotten from the numbers (y-values).
The formula for common ratio is given by;

Therefore, the common ratio is 3.
 
        
             
        
        
        
The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12
        
                    
             
        
        
        
By looking at the y values of a function or on a graph
 
        
             
        
        
        
Answer:
5x/2
Step-by-step explanation:
Say the mystery number is "x"
5 times that = 5 * x = 5x
Then the quotient (that means the result of division, so divide!) of that and 2 would give you: 5x/2
