Answer 1

Sol. 19) 2x, x+10, 3x+2 are in AP which means their d is same consider 2x as first number, x+10 as second number and 3x+2 as third number
So, 3x+2-(x+10) = x+10-(2x)
3x+2-x-10=x+10-2x
Which gives x=6
So the first number is 2x which is 12
Second number is x+10 so it is 16
Third number is 3x+2 so it is 20
And the common difference d is 4
