Question

if X + 1, 3 X and 4 x + 2 are
in AP then find the value of x ​

Answer 1

Answer:

X=3

Step-by-step explanation:

X+1,3X and 4X+2 are in A.P

then, common difference are equal

Then, D=3X-(X+1)

          D=3X-X-1

           D=2X-1  _(1)

D=(4X+2)-3X

D=4X+2-3X

D=X+2  _(2)

put equation (1) equal to equation(2) beacuase in A.P common difference are equal

2X-1=X+2

2X-X=2+1

X=3
