This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.
So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.
There will be 40 mosquitoes after ten months.
Answer:

Step-by-step explanation:

, and
. Subtracting this from the numerator gives a remainder of

, and
. Subtracting this from the previous remainder gives a new remainder of

is not a multiple of
, so we're done. Then
