The population of a city increased by 5.2% for the year 2014
At the beginning of 2015 the population of the city was 1560000
Lin assumes that the population will continue to increase at a constant rate of 5.2% each year.

(1) Use Lin’s assumption to work out the year in which the population of the city will reach 2000000

(2) If Lin’s assumption about the rate of increased of the population is too low, how might this affect your answer to (1)?
