Answer:
800 crickets.
Step-by-step explanation:
If the population starts at 50 crickets and doubles every 3 months that's 100 crickets every three months.
There are 12 months in a year.
So, we have to multiply 100 by 4.
That gets us 400.
So that is 400 crickets each year.
Since it is 2 years it would be 800 crickets.
Hope this helps!
This is a Geometric Progression problem.
We can use the formula
= a1 + [tex]q^{n-1}[/tex]
= 50 x 2^(8-1)
50 is starting number
2 is doubled
8 is how many sets of 3 months in 2 years
= 50 x 2^(7)
= 50 x 128
= 6400
