Textbook Question

Chapter 14.3, Problem 80ES

In Exercises 79-80, you will develop geometric sequences that model the population growth for California and Texas, the two most-populated US states

80. The table shows the population of Texas for 2000 and 2010, with estimates given by the U.S. Census Bureau for 2001 through 2009.

Year	2000	2001	2002	2003	2004	2005
Population in millions	20.85	21.27	21.70	22.13	22.57	23.02

Year	2006	2007	2008	2009	2010
Population in millions	23.48	23.95	24.43	24.92	25.15

Divide the population for each year by the population in the preceding year. Round to two decimal places and show that Texas has a population increase that is approximately geometric.
Write the general term of the geometric sequence modeling Texas's population, in millions, n years after 1999.
Use your model from part (b) to project Texas's population, in millions, for the year 2020. Round to two decimal places.
