Answer 2

Answer:

x= 4

Step-by-step explanation:

In AP,

The common difference is same between any two terms.

common difference = term2- term1 or term3-term2

hence, term2 - term1 = Term3-term2

that is,

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

on opening the brackets

we get, 4x-1 - 2x -1 = 5x +1 -4x +1

on simplifying,

2x-2 = x +2

that is ,

2x -x = 2+2

hence,

x = 4
