Answer:
f(5) = 3200
Step-by-step explanation:
Using the recursive formula to generate the terms, that is
f(2) = 2 × f(1) = 2 × 200 = 400
f(3) = 2 × f(2) = 2 × 400 = 800
f(4) = 2 × f(3) = 2 × 800 = 1600
f(5) = 2 × f(4) = 2 × 1600 = 3200
 
        
                    
             
        
        
        
 2(2.2)(3.0) + 2(2.2)(7.5) + 2(7.5)(3.0) 
    13.2                    33                 45
Theres the work the answer is (4) 91.2
