Answer:
formula - if a ,b,c are in AP
then → 2b = a +c
so,
2( x +10) = 2x + 3x + 2
=> 2x + 20 = 5x +2
=> 20 -2 = 5x - 2x
=> 18 = 3x
=> x = 18/3 = 6
so, the value of x is 6

Step-by-step explanation:
Since 2x,x+10 and 3x+2 are in AP
Therefore the common difference must be same.
So x+10-2x=3x+2-(x+10)
-x+10=3x+2-x-10
-x+10=2x-8
-x+10-2x+8=0
-3x+18=0
-3x=-18
x=−18−3
x=6
