What is the geometric sequence of

250, 100, 40, 16

i will mark

times 2 divided by 5

Step-by-step explanation:

625(2/5)=250

250(2/5)=100

100(2/5)=40

40(2/5)=16

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
