Question

If x, x-2and 3x are in an ap, then find the value of x

Answer 1

Answer:

Ans is -2

Step-by-step explanation:

If they are in ap then the difference of consecutive terms are equal...

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

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

4 = -2x

x = -2

Answer 2

Answer:

Let me help you for this question.....

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

=> Condtion for AP : 2( Middle term ) = Sum of the Other 2 terms

=> 2(x - 2) = x + 3x

=> 2x - 4 = 4x

=> 2x = -4

=> x = -2

Therefore the terms are : -2, -4, -6
