Question

Help ASAP! Will fan, medal, WHATEVER it takes to get help! PLEASE!

Answer 1

Part 1: Create a scenario for an arithmetic sequence. For example, Jasmine practices the piano for 20 minutes on Monday. Every day she increases her practice time by 10 minutes. If she continues this pattern, how many minutes will she practice on the 7th day? Be sure to fill in the blanks with the words that will create an arithmetic sequence. Use your scenario to write the function for the 7th term in your sequence using sequence notation.

Day n: 20 + 10(n - 1)



Part 2: Create a scenario for a geometric sequence. For example, Anthony goes to the gym for 30 minutes on Monday. Every day he increased his gym time by 5 minutes. If he continues this pattern, how many minutes will he spend at the gym on the 5th day? Be sure to fill in the blanks with the words that will create a geometric sequence. Use your scenario to write the formula for the 5th term in your sequence using sequence notation.

Day n: 30 + 5 (n - 1)


Part 3: Use your scenario from part 2 to write a question that will lead to using the geometric series formula. Use the formula to solve for Sn in your scenario.

Answer 2

I already have the equations down, just need the last part.
