Answer:
The common difference is -1/2
Step-by-step explanation:
we know that
In an Arithmetic Sequence the difference between one term and the next is a constant and is called the common difference
we have
a1=2/3
a2=1/6
a3=-1/3
a4=-5/6
so
a2-a1=1/6-2/3=-1/2
a3-a2=-1/3-1/6=-1/2
a4-a3=-5/6-(-1/3)=-5/6+1/3=-1/2
therefore
The common difference is -1/2
6/12=1/2
Therefore 6/12 is equal to 50/100 or 50%

Answer:
M = 1 and M = -7.5
Step-by-step explanation:
The distance between A and B is 6 - (-1.5) = 7.5
Point 1: M is between AB. Since AM:MB = 1:2 then AM:AB = 1:(1+2) = 1:3
that means AM = 7.5 / 3 = 2.5
So M is at -1.5 + 2.5 = 1
Point 2: A is between MB. Since AM:MB = 1:2 then AM:AB = 1:(2-1) = 1
That means AM = AB = 6
So M is at -1.5 - 6 = -7.5
