Question

if 8,x,20 are in ap the value of x is​

Answer 1

Step-by-step explanation:

8×5/2=20

40/2=20

20 =20

Answer 2

AP : a₁ , a₂ , a₃

AP : 8 , x , 20

As we are that the terms are in AP so the common difference will be same.

Common Difference (d) = a₂ - a₁

a₂ - a₁ = a₃ - a₂

⇒ x - 8 = 20 - x

⇒ x + x = 20 + 8

⇒ 2x = 28

⇒ x = 28/2

⇒ x = 14

∴ The value of x is 14.
