i've heard that if in a population each pair has 4 children, then after 4 generations it's a 1600% increase..
I suppose after 1 generation it is 200%, and each successive generation is 200%, and they multiply 200%^4 But, if I try it out with figures like this, I never get 1600%
suppose a population of 10
g g1 g2 g3 g4 10 20 40 80 160
So each generation is double the previous, and from the start of g, population of 10, each of 4 generations g1-g4 have 4 children.
10+20+40+80+160=310
(310-10)/10 = 3000%
Not 1600%
Howcome i'm not getting 1600%?
