Question

If the number x-1,x+3, 3x-1,..are in A.P find then find value of are x​

Answer 1

Answer:

If x-1, x+3, and 3x-1 are in AP then the value of x is 4

Step-by-step explanation:

If x-1, x+3, and 3x-1 are in AP, then their common difference is the same

That is, (x+3)-(x-1)=(3x-1)-(x+3)

x+3-x+1=3x-1-x-3

4=2x -4

2x=8

x=8/2=4

So the value of x is 4
