Question

If 8, x, 20 are in arithmetic progression, the value of ʻxʼ is​

Answer 1

Answer:

x=(8+20)/2

x=28/2

x=14

Answer 2

Answer:

The value of 'x' = 14

Step-by-step explanation:

Given,

8,x,20 are in arithmetic Progression

To find,

The value of 'x'

Recall the concepts:

If a,b,c are in Arithmetic progression(A.P),

then  b-a = c-b = d, where'd' is called the common difference on the AP

Solution:

Since 8,x,20 are in AP

x-8 = 20-x

x+x = 28

2x = 28

x =14

∴ The Value of 'x' = 14

And the AP is 8,14,20

Answer:

The value of 'x' = 14
