Answer:
The question is not written, so i will answer in a general way.
We know that we start with two people, Emz and Colt.
Let's define the function:
P(n) = The number of people helped in each iteration.
such that n is the number of each event (n = 1 is when Emz and Colt help 5 people each, n = 2 is when those helped people help more people, and so on)
We know that:
P(1) = 10
Because we have 2 persons helping 5 each, 2*5 = 10.
Now, each one of these 10 persons help 5 people, then:
P(2) = 10*5 = 50
Now each of these 50 people help 5 more, then:
P(3) = (10*5)*5 = 10*5^2
We already could see the pattern, such that:
P(n) = 10*(5)^(n - 1)
This equation represents the number of people helped in each iteration.
