Answer: bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
Step-by-step explanation:
It looks like geometrical sequence, each next generation is three times greater than previous one. So the r of this sequence is 3.
The first generation has 150 representatives, so b1=150
The formula of geometrical sequence is bn=b1*r^(n-1)
(in our case bn is a quantity of bacteria in generation n)
so bn= 150*3^(n-1)( bn is a quantity of bacteria in generation n)
