Answer:
6.7 in bcoz 4-3.2=0.8 and 7.5-0.8=6.7
Y is between X and Z
The value of d=2 and the value of YZ = 16
Given :
Y is between X and Z.
XY = 11d, YZ = 9d – 2, XZ = 5d + 28
We need to find the value of d
we know that Y is between X and Z
So, 
Replace the given expression and solve for d

The value of d=2
Now we find out YZ using d=2

The value of YZ is 16
