Here a = 2, b = -2, c = -1
b^2-4ac = (-2)^2 - 4(2)(-1)
= 4 +8
= 12
Answer:
<em>The amount of rabbit after 1 year will be </em><em>320</em><em>.</em>
Step-by-step explanation:
A gardener brought 5 rabbits, after 2 months rabbits became 10.
The growth continues on the same ratio.
This represents a geometric sequence with 1st term as 5 and common ratio as 2.
As we have to find the amount of rabbit after 1 year, so the we have to find
th term. As the time difference between each counting is 2 months, so we divided 1 year or 12 months of time by 2.
nth term in a G.P is,

Putting the values,

-3 is a negative number and 2 is a positive
