Question

find the value of x if 3x-4,4x-7, 7x-3 are an AP​

Answer 1

Answer:

-7/2 or -3.5

Step-by-step explanation:

As they are in A.P

A + C = 2B

(3x - 4) + (7x - 3) = 2(4x-7)

10x - 7= 8x -14

2x= -7

Therefore x = -7/2 or -3.5

Answer 2

Answer:

-7/2 or -3.5

Step-by-step explanation:

Since they are in an AP(Arthimetic Progression)

4x-7-(3x-4)=d-(1)

7x-3-(4x-7)=d-(2)

since (1) and (2) are equal

so 4x-7-3x+4=7x-3-4x+7

x-3=3x+4

2x=-7

x= -7/2.
