Ответ:
y=10
Step-by-step explanation:
As you can see, the order when x=2 and z=4, is y=x+1, z=y+1, therefore y was 3.
Then, you can find y when x=8 and z=12 by:
12-8=4 (the difference between z and x)
and then divide 4 by 2 (the number of intervals between x, y, and z)
then get 2 (as the difference between x and y.
The answer is 8+2=10.
Hope this helps!
