New here so apologies if this is not quite allowed. Yesterday our department had a meeting in one of our conference rooms on campus. When we arrived the room was empty, but there were three puzzles written on three panels of the whiteboard. Two of them were fairly straightforward number sequences, but we were all left stumped on the third. showing triangle = 3, square = 4, hexagon = 5, circle =?
Would love any suggestions as to a solution or why the hexagon is 5. Thanks!
