Answer 2

Answer:

Value of x is 6

Step-by-step explanation:

We are given that,

The expressions $3x-1,x+2,x-7$ are in AP.

Since, they are in arithmetic progression. We get,

Their common difference is equal.

i.e. $(x+2)-(3x-1)=(x-7)-(x+2)$

i.e. $-2x+3=-9$

i.e. $-2x=-12$

i.e. x= 6

Thus, the value of x is 6.
