Answer:
a = 20
Step-by-step explanation:
The mean is calculated as
mean = 
           =  =
  = 
Then
 = 27 ( multiply both sides by 5 to clear the fraction )
 = 27 ( multiply both sides by 5 to clear the fraction )
115 + a = 135 ( subtract 115 from both sides )
a = 20
 
        
             
        
        
        
Answer:
Step-by-step explanation:
This is an arith. sequence.
The first term is 3 and the common difference is 1
Thus, the general formula for the nth term of this sequence is:
a(n) = 3 + 1(n - 1)   This matches Answer A
 
        
                    
             
        
        
        
The answer is f(x) will eventually exceed g(x) because f(x) is an exponential function.
