Question

if 2x+1, x+1, 4x-5 are in ap , then find x​

Answer 1

Answer:

since these numbers are in AP

THEREFORE common difference is same

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

- x = 3x - 6

- 4x = - 6

x = 3/2

Answer 2

Answer:

Pls mark me as brainliest

Step-by-step explanation:

If 2x+1, x+1, 4x-5 are in AP then

d = x+1 - 2x -1 = -x

d = 4x-5 - x -1 = 3x - 6

As it is in AP therefore

-x = 3x - 6

4x = 6

x = 3/2
