Some one might like this.
20² + 21² = 29²

@Optionparty

could i ask is there a rule behind this?😀

@Optionparty Math checks out. What is the geometry of this that makes it possible? What is the pattern of the jump from 20 to 21 to 29? 21^2 + 29^2 = 1282, which doesn’t have a whole number square root. What is the next such symmetry in this series? Or is there one?
Sorry, I’m not a mathematics person, just curious.
