torm of a progression is (4n
progression is (10) bal​

Answer 1

Answer:

Step-by-step explanation:

(5x + 2), (4x - 1 ) (x + 2 )

arithmetic mean : 2b = a + c

here , a = 5x +2 , b = 4x - 1 , c = x + 2

so substituting these values :

2 ( 4x - 1 ) = 5x + 2 + x + 2

8x - 2 = 6x + 4

8x - 6x = 4 + 2

2x = 6

x = 6/2

x = 3
