Question

In 1995 the People’s Republic of China grew at an annual rate of 1.5%. Which recursive formula could be used to predict the population of China?

A Pn= Pn-1 +1.5

B Pn=Pn-1(0.015)

C Pn=Pn-1 (1.015)

D Pn=Pn-1 +1.015

Answer 1

As there is an annual growth rate we must multiply P_n-1 by a factor greater than 1.

Therefore must be C

We multiply by (1 + 0.015). 1 is always constant here. + because it is growth. 1.5 % = 1.5/100 = 0.015
