Which sequence is not equivalent to the others:

1. a reflection across the y axis, fallowed by a reflection across the x axis, then a 90 degree clockwise rotation about the origin 

2. a 90 degree clockwise rotation about the origin  and then a 180 degree clockwise rotation about the origin

3. a reflection  across the  x axis, fallowed by a 90 degree counterclockwise rotation about the origin,and a reflection across the x axis

4. a 90 degree counterclockwise rotation about the origin
