Could someone explain the proof of Cake Numbers?












0












$begingroup$


Is there a graphical, or visual, proof of the Cake Numbers? And if so, could someone explain it to me? I am looking for an explanation similar to that for the Lazy Caterer's sequence on Wikipedia: https://en.wikipedia.org/wiki/Lazy_caterer%27s_sequence
Thanks

    The Cake Numbers $1,2,4,8,15,26,...$ describe how many pieces can be formed by making $nge 0$ straight cuts into a cake or a ball. The formula is $binom{n}{0}+binom{n}{1}+binom{n}{2}+binom{n}{3}$, with terms being zero of course when the second argument exceeds the first.
