I think I solved it but it will take me a moment to write down. I haven’t written anything for a while because I’ve been depressed so sry if it’s messy and idk if the proof is correct

Like this maybe? What do you think?
nice solution! i like the geometrical arguement with the paths
Thank you ^^ This was a fun problem and it got me to actually do some maths after taking a break for a while
you can show that x_n is always of the form x_2/2^m but idk how to proceed from then
