Answer: on point -10
Step-by-step explanation:
Because 2*-5 is -10.
I believe the answer would be A because an arithmetic sequence consists of a constant difference between terms.
![5y^2 - 80 = 5(y^2-16) = 5(y - 4)(y + 4)](https://tex.z-dn.net/?f=5y%5E2%20-%2080%20%3D%205%28y%5E2-16%29%20%3D%205%28y%20-%204%29%28y%20%2B%204%29%20)
LCM of 5(y - 4)(y + 4) and (y + 4) is 5(y - 4)(y + 4)
