Victor and Vicky bought a cake and ate it in the following way: One morning Victor ate half of the cake, in the evening Vicky ate the remaining half of the cake. This process continued in the same way for 
days, each eating half of the cake they found. On the morning of the fifth day, Victor ate what was left of the cake. What proportion of the cake did Victor eat in the 
days?

Private Forum for Geometry Study

Hi all,
I've recently been trying to improve my skill at competition math, but I consistently struggle with geometry. Since doing math is more fun and motivating with others, I've created the GeoPrepClub. This is a private forum to increase geometry skill and help others increase theirs: we'll have problems, marathons, and much more. This is similar to forums such as "AMC8 Prep Buddies" by PatTheKing, but is focused exclusively on this subject. We welcome all skill levels and hope those with greater mathematical knowledge can assist those lacking in it.
If this sounds interesting to you, sing up below and I'll let you know once I've added you. Although the forum may not have much now, that's because I've only just released it, and I hope once I build a community, It will be a very useful and motivating space for those interested in improving their geometry. The link is
here.
I look forward to seeing you all in the forum!
