A certain organization consists of five leaders and some number of regular members. Every year, the current leaders are kicked out of the organization. Next, each regular member must find two new people to join as regular members. Finally, five new people are elected from outside the organization to become leaders. In the beginning, there are fifteen people in the organization total. How many people total will be in the organization five years from now?

By geometric series, the number of members after five years is 5^5*15 - 5^5*5 = 31250.

Lol what a liar, this guest dodn't even put a formula, he tries to purposely put in a wrong answer, I solve it later, and this is out of the world!

 

 

😂 

 

edit: I mean that this is the standard formula for a cheap answers guest

 

Using "formula", the answer is "this", it completely is some stupid fake information, it's far from the way to answer a problem.

It is a confusing question but this is my interpretation

 

 

 

after leaders other members
NOW 5 10
after a  year 5 3*10=30
after 2 years 5 3*30=90
after 3 years 5 270
after 4 years 5 810
after 5 years 5 2430

 

5+2430 = 2435
