I would say B. By multiplying the first equation by -5, you create -5y. If you add that to the second equation, your cancelling out the 5y term, and get a new equation with only z and a constant.
A geometric sequence is one that is multiplied by the same number, and an arithmetic sequence is one that is added by the same number.
2 * 2 = 44 * 2 = 8 - This works, so will be geometric
I would say D but I’m not sure sorry
