whose partial sums are given. Calculate the sum of the series a n n=1 S = 5 - 9(0.8)7 nThis question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise Determine whether the geometric series is convergent or divergent. If it is convergent, find its sum. 9_11+ 121 _ 1331 + 9 31 To see 9 11 + 121 1331 + - - - as a geometric series, we must express it as 2 air" - 1. 9 81 n=1 n ar n1' on For any two successive terms in the geometric series 2 ar" 1, the ratio of the the two terms, ar n=1 simplies into an algebraic expression given by |:| . Determine whether the geometric series is convergent or divergent. 49 343 8 + 7+ + 8 64 O convergent O divergent If it is convergent, find its sum. (If the quantity diverges, enter DIVERGES.)Consider the following geometric series. 2+.4+0.08+0.016+--- Find the common ratio. M =:] Determine whether the geometric series is convergent or divergent. convergent O divergent I If it is convergent, nd its sum. (If the quantity diverges, enter DIVERGES.) E
