Please help me solving these questions they are annuity as geometric series

Please make writing clear to understand

Show your thinking In previous activities, you created screencasts to demonstrate your understanding of a variety of concepts. In this activity, you will create screencasts to demonstrate your understanding of sequences and series. Create screencasts for each of the following. 1. For the arithmetic series = + 10 + 5 + ..., calculate tio and $10. 2. For the geometric series 100 - 50 + 25 - ..., calculate to and $10. 3. Using Pascal's Triangle, expand (3m - 4)4. 4. You decide that you want to purchase a Tesla SUV. You borrow $95, 000 for the purchase. You agree to repay the loan by paying equal monthly payments of $1, 200 until the balance is paid off. If you're being charged 6% per year, compounded monthly, how long will it take you to pay off the loan? 5. Your family borrowed $400, 000 from the bank to purchase a new home. If the bank charges 3.8% interest per year, compounded weekly, it will take 25 years to pay off the loan. How much will each weekly payment be? For your screencasts, you may use the formulas when solving for present value and future value of annuities, or you may use the interactive from the lesson. If using the interactive be sure to show all of your variable inputs, and clearly describe how you used the interactive to solve for the unknown. Submit your screencasts to your teacher.
