4 to the 1st is 4
4 to the 2nd is 16
4 to the 3rd is 64
<span>4 to the 4th is 256
hope that helps</span>
        
             
        
        
        
add 4 each time
the nth term is a_n or f(n)
the next term after that is a_{n+1} or f(n+1)
so each term is 4 more than previous
basically
a_{n+1}=4+a_n or
f(n+1)=4+f(n)
same thing
 
        
                    
             
        
        
        
If we make s = Senior tickets,  
11s+1s
to find the values of c and s,w 
If we express s in terms of c on t 
s=21-2c
replacing this value on the first equation, we obtain 

Placing c=6 on s=21-2c, we have 

Thus the senior ticket costs $9 and the child ticket cost $6
