Suppose that you are responsible for predicting the cost of constructing a new office building. You find that the first story costs 500 dollars per square meter of floor space, and the second story costs 600 dollars per square meter. Assume that the costs per square meter form a geometric sequence.
a. Find the cost of the 10th story.
b. Write the equation that corresponds with this problem
r = 600/500 = 1.2
T10 = 500*1.2^9 = 2580
Tn = 500*1.2^(n-1)
