1. The first term in geometric sequence is 8, and the nineth term is 1/32.
Answer (1)
Answer: Common Ratio = 1/2Step-by-step explanation:8 (first term)8 x 1/2 = 4 (second term)4 x 1/2 = 2 (third term)2 x 1/2 = 1 (fourth term)2 x 1/2 = 1/2 (fifth term)1/2 x 1/2 = 1/4 (sixth term)1/4 x 1/2 = 1/8 (seventh term)1/8 x 1/2 = 1/16 (eighth term)1/16 x 1/2 = 1/32 (ninth term)Therefore 1/2 is the common ratio
