The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 30 and the common rati

Alchen [17]

The sum will be:

sigma(i = 1 to infinity, 30*(2/5)^i)

-> $\lim_{i \to \infty} \frac{30(1- \frac{2}{5}^{i} )}{ \frac{3}{5} }$

Which is equal to 30/(3/5) = 50
