I think it's some sort of a progression, but I'm not sure

1/2x +1/2 (1/2x + 1/2 (1/2x +1/2 (1/2x + ... = y, then x = ?

Would really appreciate, if you'd help me out on this one guys sad

Hi;

You could notice

That the boxed region is just y again and say,

x = y

Or you can expand it out,

x = y

Welcome to the forum.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
