Common ratio = -25/-125 = 1/5 answer
They all have the same slope do it with the equation (y2-y1)/(x2-x1) so if you do it for all of them for example (80-40)/(4-2)=20 and the same answer goes to every single combination.
Hope this helps!
First, find the volume. For a square polyhedron, the formula for the volume is the following:
<span>Volume=length×width×height</span>
