If I have 60 individuals that can potentially have 2 children each ...and the offsprings would continue to have 2 children for 8 generations ...how many decendents would I have today ?
Ok sorry
I genuinely thought it was a riddle.
I will re-phrase the question to what I now think that you meant.
60 individuals have 2 children each and each of their descendants have 2 children each. How many descendents will be in the 8th generation.
First generation = 60
second gen = 120
third gen = 240
4th = 480
5th = 960
6th = 1920
7th = 3840
8th = 7680
This is an example of a geometric progression (GP for short)
The number of people in the nth generations (sometimes called T n or a n = a*r (n-1)
where 'a' is the original number of people and r is the common ratio which is the multiplying factor needed.
In this case a = 60 and r= 2 and you want T 8
T 8 = 60 * 2 (8-1)= 60 * 2 7 = 60 * 127 = 7680
I hope that this is the answer that you wanted. If not you can ask again.
