Answer: A. f(n) = 4 ∙ 2n-1
Step-by-step explanation:
because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
1,500/1.2 = 1,250
 
        
                    
             
        
        
        
0.06x+0.09 (1200-x)=96
Solve for x
X=400 at 6%
1200-400=800 at 9%
