Please post what you have done.Hi, I have some questions on geometric series.
Estimates are produced for the number of babies born worldwide each year. The estimates for 2004 and for 2008, given in thousands of births to the nearest thousand, were 130350 and 137804 respectively. Assume that successive yearly estimates are in geometric progression.
a) Find the annual percentage increase in the number of births.
b) Find the estimates for 2006 and 2011 (to the nearest thousands)
I worked out a) correctly, the answer being 1.4%, but I'm not sure that my method was completely reliable, so I'd really appreciate it if someone could me the proper method. Also, the answers for b) are 134000, and 144000.
Any help would be greatly appreciated
