Answer 2

Answer:

x = 10/3

Explanation :

Common difference will be same.

Second term ( x+10) - First term (2x) = Third term ( 3x +10) - second term ( x+10)

x+10 - 2x = 3x +10 - x - 10

-x = 2x - 10

3x = 10

x = 10/3

For Verification : Put x = 10/3,

Then, 1st term = 20/3

2nd term = 40/3

3rd term = 20

Their Common difference is 20/3.
