Answer 1

Hey

Here is your answer,

A.P : 2x, x+10 , 3x+2

In an A.P. Second term - first term = third term - second term

x+10-(2x) = 3x+2-(x+10)
x+10-2x = 3x+2-x -10
10-x = 2x -8
-x -2x=-8-10
-3x=-18
x=-18/-3
x=6

Terms = 2x = 12
X+10 = 16
3x+2 = 18+2 = 20

Hope it helps you!

Answer 2

Hey mate,

Here is ur answer,

2x , x+10 , 3x+2.

In AP common difference is constant.

=> a2-a1 = a3-a2.

=> x+10-2x= 3x+2-x-10.

=> 10-x = 2x-8

=> 3x =18.

=> x=18/3.

=> x=6
