Question

18. If x, x - 2, and 3x are in AP, then find the value of x.​

Answer 1

x , x-2 , 3x are AP then,

x-2-x = 3x- x+2

-2 = 2x +2

-4 = 2x

-2 = x

x = -2

Answer 2

Step-by-step explanation:

we define AP as the series of numbers which have a common difference in their progression.

Given that x , x-2 , 3x are in AP

we can conclude that ,

(x-2)-x= 3x-(x-2)

x-2-x= 3x-x+2

-2=2x+2

2x= -4

x=-2

SINCE WE HAVE THE VALUE OF X .

WE CAN FIND OUT THE AP

WHICH COMES OUT TO BE :

-2,-4,-6....
