Question

Find the 8th term of the geometric sequence whose common ratio is

1/3
and whose first term is 5.

Answer 1

Answer: 5/2187

Step-by-step explanation: The equation for geometric sequence is (a (subroot) n = a (subroot) 1) x ratio^(n-1).

• a (sub) n = a (sub) 8
• a (sub) 1 = 5
• ratio = 1/3
• (n-1) = 7
