Title: From A to G: Arithmetic into Geometric Progressions through Riordan Arrays

Abstract: Is it possible to move from an arithmetic sequence to a geometric sequence via a Riordan array transformation? Spoiler: Yes! Enjoy some free juice boxes and snacks as we discuss a paper by Donatella Merlini and Renzo Sprugnoli exploring both an algebraic and combinatorial proof of identities that allow us to move from one type of sequence to the other.
