Tutorial Exercise Determine whether the geometric series is convergent or divergent. If it is convergent, find its sum. 81 729 8 - 9+ + 8 64 Step 1 81 729 8 To see 8 - 9 + + . . . as a geometric series, we must express it as 8 64 Earn - 1. n = 1 arn For any two successive terms in the geometric series _ arn - 1, the ratio of the the two terms, arn - 1 n = 1 simplifies into an algebraic expression given by Submit Skip (you cannot come back)
