The statement that,

"The population of a town in three consecutive years are 5000, 7000 and 8400 respectively. the population of the town in the fourth consecutive year according to geometrical increase method is 10920." is correct.

geometrical increase method is based on the assumption that percentage growth rate is constant i.e. dP/dt=kP; lnP= lnP0+kt.
