Answer:
329.5 
Step-by-step explanation:
From the table we see that the common difference d  = 0.5 - (-6.5)
= 7,  and 7.5 - 0.5 = 7. Also 14.5 - 7.5 = 7.
The first term a1 = -6.5.
The nth term = a1 + (n - 1)d  so for our sequence we have:
49th term =  -6.5  + (49 - 1)7
= -6.5 + 48 * 7
= -6.5 + 336
= 329.5   (answer).
 
        
             
        
        
        
-25 15/19 + 9/1
 get a common denominator of 19
 they multiplied 9/1 * 19/19 = 171/19
-25 15/19 + 171/19 =
change the mixed number to an improper fraction
(19* 25 +15)/19 = 490/19
-490/19 + 171/19 =
add together
-319/19
now convert the improper fraction back to a mixed number
19* 16 =304  319-304=15
-319/19 =-16 15/19
