Question

state the common ratio, then, write the next 3 term of this geometric sequence. -12 500, 2500, -500

Answer 1

@ori16 Divide -12500 by 2500 and post what you get, okay?
If you enter "(-12500/2500)=" in the Google search field, the Google calculator will pop up the result.

I think the answer to that question may be the common ratio. We'll test it.

Answer 2

If what you get is the same result as "2500/(-500) =" then we have found the common ratio.
