Answer:
Step-by-step explanation:
This is an arithmetic sequence.
Each term is obtained by subtracting 16 from the previous term
common difference = 2nd term - first term
= 50 - 66
= -16
5th term = 18 - 16 = 2
6th term = 2 - 16 = -14
7th term = -14 -16 = -30
8th term = -30 - 16 = - 46
66, 50 , 34 , 18 , 2 , -14, -30 , - 46........
