Determine whether the sequence appears to be an arithmetic sequence. If so, find the common difference and the next three terms. 7, 3, −1, −5, ...

Arithmetic = going up or down the same units: going down by -4; true
Common difference = how much it is going up: -4

Solution: yes it’s arithmetic. The common difference is -4. The next three terms is -9, -13, -17

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
