A piece of paper has an area of 81cm. A strip is cut off that is 1/3 the original area. From that strip is cut off that is 1/3 the area of the first, and so on. Here is a graph and table representing sequence k, where k(n) is the area in square centimeters of the strip of paper after n cuts. A. Is the sequence geometric or arithmetic? Explain how you know
B. Write a recursive rule for the sequence. Be sure to include f(n) and f(n-1) in the rule
C. What type of “n” value do you notice will work for the sequence? Hint: use the graph
D. What type of “n” value do you notice will not work for the sequence? Hint: use the graph
