The answer to this question is -.5. We can determine the common difference by just subtracting the first number to the second number 14 - 14.5 is equal to -.5, 14.5 - 15 is equal to -.5 and so on.
This sequence is arithmetic and the common difference is -.5

3) 0.5(12m-22n)=0.5(12m)-0.5(22n)
=6m-11n
4) 2/3(18x+6z) =2/3(18x)-2/3(6z)
=12x-4z
5)2x+12=2(x+6)
6)12x+24=12(x+2)
