Question 1111187
Alright. Given that this is an arithmetic sequence, so the difference between the second term and the first term is equal to the difference between the third term and the second term. 

Henceforth, 
T3 - T2 = T2 - T1
4x+6-2x = 2x-(x-5)
2x+6 = x+5
X=-1

Now we substitute x into the equations. 
The first term is x-5, hence 
-1-5=-6

T2 
= 2x
= 2(-1)
= -2

T3
= 4x+6
= 4(-1)+6
= -4+6
= 2

Hence, the three terms are -6, -2 and 2 respectively.
