Answer:

this is the he answer according to the information given

Answer:

x = 10, y = 20

Step-by-step explanation:

Because this is a geometric sequence, we'll call the rate of change z. Because 40 is 3 terms away from 5, we can write 5 * z * z * z = 5z³ = 40.

z³ = 8 → z = 2

Now, we simply multiply 5 by 2 to get x, which is 10, and then we multiply x by 2 to get 10 * 2 = 20 for y. Hope this helps!

Final answer:

To find the values of x and y in the given geometric progression, we use the concept of a common ratio. By setting up equations based on the definition of a geometric progression, we can solve for x and y. In this case, x is 10 and y is 20.

Explanation:

To find the values of x and y in the given geometric progression, we need to identify the common ratio between the terms. In a geometric progression, each term is obtained by multiplying the previous term by the common ratio. Therefore, we have:

1. 
   
2.  
3. 5 * r = x
4. 
   
5.  
6. x * r = y
7. 
   
8.  
9. y * r = 40

From the first equation, we can substitute x as 5 * r in the second equation:

5 * r * r = y

Then, we substitute y as 5 * r * r in the third equation:

5 * r * r * r = 40

Simplifying the equation, we get:

r^3 = 40/5 = 8

Taking the cube root of both sides:

r = 2

Substituting this value of r back into the equations, we find that x = 10 and y = 20.
