1. ## series problem (calc II)

World oil consumption can be estimated to be approximately 75.747 million barrels per day in 2002 and to be increasing at approximately 0.27 percent per year. Let be the daily world oil consumption years after 2002.

a) Find a formula for Sn:

b) Find a formula for Sn - S(n-1)

2. $S_n = \frac{a}{1-r}$
r = 0.27
a = 75.747
