Step-by-step explanation:
a(n) = a +(n-1)d
a=-5
d=5
a(n) = -5 +(n-1)5
       =-5+5n-5
      =5n-10
a(50) = -5 +(50-1)5
         = 240
hope this helps
 
        
             
        
        
        
Please find the attached file for a better understanding of the explanation given here.
the attached diagram is a generated image of the first fifteen rows of a pascal's triangle. As can be seen from the image, the least four-digit number in the first fifteen rows of pascal's triangle is 1001. 
In the diagram attached that number is present in the very last row and is highlighted using a yellow rectangle.
 
        
             
        
        
        
Your suppose to round the percent!!!!!!
        
                    
             
        
        
        
Exponential growth is 
F=P(1+r)^t
F=future amount
P=present amount
r=rate
t=time in years
rate=2%=0.02
therefor the equation is 
f(x)=23,000(1+0.02)^x
f(x)=23,000(1.02)^x
where x=time in years from 2012
