I think you mean 
basically that measn yo divide that term by the previous term
ok
a3=a1/a2=1/2
a4=a3/a2=(1/2)/2=1/4
a5=a4/a3=(1/4)/(1/2)=1/2
a6=a5/a4=(1/2)/(1/4)=2
a7=a6/a5=2/(1/2)=4
a8=a7/a6=4/2=2
a9=a8/a7=2/4=1/2
a10=a9/a8=(1/2)/2=1/4
ok, so notice a pattern
a3=a9
a4=a10
I therefor conclude that
where w is a whole number
and n>2ok, so
241=6*39+7
so therefor
therefor the 241th term is same as a7 or 4
I say a241 is 4

When a shape is rotated, it must be rotated through a point.
- <em>90 degrees counterclockwise rotation negates the y-coordinates, and then swap the x and y-coordinates</em>
- <em>Chanel is incorrect</em>
The rule of 90 degrees counterclockwise is:
This means that:
- <em>The y-coordinate is negated</em>
- <em>Then the y and x coordinates are swapped</em>
<em />
However, Charlies transformation is incorrect.
- This is so because, the shape was not rotated, but instead it was reflected across the x-axis.
- Then, the shape was dilated
Using points L and Q
When L is reflected across the x-axis.
The rule is:
So, we have:
Next, it is dilated by 2.
The rule of this is:
So, we have:
From the diagram, the coordinate of Q is:
Same as the calculated point
Hence, Chanel is incorrect
