Arithmetico-Geometric Series Visualized (visual proof using Gabriel's Staircase)

[@BrianAmedee]

This is an amazing abstraction. Awesome job!

[@MathVisualProofs]

Thanks! Swains visual proof is one of my all time faves :)

[@NonTwinBrothers]

Woah wait, no way

[@MathVisualProofs]

Yes way! :)

[@jakobthomsen1595]

Cool!

[@DitDede]

Nice. Alternatively (not a visual proof), the left sum is the derivative of r/(1-r)

[@MathVisualProofs]

Yes I love that proof too.
