Find the common ratio for the following sequence 20, 10, 5, 2 1/2

0.5

Step-by-step explanation:

We are given the following sequence and we are to determine its common ratio:

20, 10, 5, 2 1/2

In  a sequence, the common ratio is the ratio of a term to its previous term.

So here, we will divide each term by its previous term to find the common ratio.

2 1/2 = 2.5 ---> 2.5/5 = 0.5

5/10 = 0.5

10/20 = 0.5

Therefore, the common ratio of this sequence is 0.5.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
