Answer:
   -2 > -6  . . .   or  . . .  R > S
Step-by-step explanation:
If you plot the temperatures of the two cities on a number line, you see that the temperature for City R is plotted to the right of the temperature for City S. This means the temperature of City S is less than that of City R.
If your inequality relates cities:
   S < R   or   R > S
If your inequality relates temperatures:
   -6 < -2   or   -2 > -6
 
        
             
        
        
        
Answer:
495
Step-by-step explanation:
In order to find the sum of the first 18 terms you have to find the 18th term and the first term using the equation given. 
a1=3(1)-1        a1=2
a18=3(18)-1   a18= 53
Then plug in 53 for an, 18 for n, and 2 in for a1 in the sum equation: Sn=n/2(a1+an)  
Sn=18/2(2+53)  Solve for sn= 495
