Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
7.
15/2= 7.5
you cant get 7 and a half action figures so round down to 7
Answer:
Step-by-step explanation:
If the given is x^2 then the degree is 2.
Degree: 4 - x^2 = 2.
It is what is on the x to the highest power. If the question was
x^3 - 3x^2 + 2x + 4
The the degree would be 3
