Example

Consider a scenario where we have the 2020 population figures of 5 major cities. Our goal is to estimate the population in the year 2030 assuming an average growth rate of 2%.

City	New York	London	Hongkong	Toronto	Los Angeles
2020 population	8804190	9002488	7960000	3998747	6197000
Growth rate	0.02	0.02	0.02	0.02	0.02
Duration	10	10	10	10	10

To achieve this, the following formula should be written in the [2030 population] node:

[2020 population]*EXP([Growth rate]*[Duration])

Result

2030 population
10753461.95
10995663.67
9722365.955
4884080.615
7569032.892
