Answer: There are 6400 bacteria that will be present after 3 hours.
Step-by-step explanation:
Since we have given that
Initial number of bacterial cells = 100
Each cell divides to form two new cells every 30 minutes.
Number of hours = 3 hrs
Number of minutes in 3 hours = 3\times 60 = 180 minutes
Number of 30 minutes in 3 hours = 
So, our equation becomes,

Hence, there are 6400 bacteria that will be present after 3 hours.
The next term of the series, 3, 10, 29, 66, 127 is 218.

3a + 4 + b + 2a + 5 + b
Group like terms:
3a+2a+b+b+ 4+ 5
5a + 2b + 4 + 5
= 5a+2b+ 9
hope this helps!
