Please HELP I've been stuck for an hour ;;
John has taken out a loan for college. He started paying off the loan with a first payment of $100. Each month he pays, he wants to pay back 1.1 times as the amount he paid the month before. Explain to John how to represent his first 20 payments in sigma notation. Then explain how to find the sum of his first 20 payments, using complete sentences. Explain why this series is convergent or divergent.

Best ResponseYou've already chosen the best response.1100 100*1.1 100*1.1^2 100*1.1^3 ... 100*1.1^19 There they are. You do the sigma notation.

Best ResponseYou've already chosen the best response.1100 + 100*1.1 + 100*1.1^2 + 100*1.1^3 + ... + 100*1.1^19 = 100(1 + 1.1 + 1.1^2 + 1.1^3 + ... + 1.1^19) = \(100\dfrac{11.1^{20}}{11.1} = 100\cdot\dfrac{5.7275}{0.1} = 5727.50\) You must be familiar with Geometric Series. Very helpful skills.
