Answer:
BC
Step-by-step explanation:
A secant is a line which intersects the circle at 2 points
In the given diagram this is BC
 
        
                    
             
        
        
        
From the explicit formula:
an=3+(n-1)8
simplifying this we get:
an=3+8n-8
an=8n-5
thus 
the recursive formula is:
an=an-1+
the missing part is the common difference which is 8
        
             
        
        
        
She will have traveled 7,388 miles.
