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).
