Answer: 1.5
Step-by-step explanation: The difference between the 2nd And 4th is 7. Divide by 2 to get 3.5. Add 3.5 to f(2) to getf(3)
The difference between f(1) and f(2) will be 3.5 and that's 5-3.5 =1.5 
F(5) is 15.5 f(6) is 19 
        
             
        
        
        
It represents the first one 3+(-1)
        
             
        
        
        
The right system of equations to describe the situation would
be on the form:
x1 = 8000 + y1*t 
and
x2 = 8000 + y2*t
where x1 and x2 represents the total money of Imogene and her
friend respectively at the end of t years.
Now for the value of amount earned, y1 and y2:
y1=8000*0.08
y2=2000*√(t-2)
