Not arithmetic because the difference between each of the terms is not the same.
S₂ - S₁ S₃ - S₂ S₄ - S₃
3 - 2 = 1 4 - 3 = 1 9 - 4 = 5
Not geometric because the ratios between each of the terms is not the same.
First you solve 2y-3y=9.
Now that you have y, then you substitute y into x-2y=3 to find X
Your solution is (-15, -9)
