I'm sure you're all familiar with pattern recognition puzzles where you have to find the next picture in a sequence. Well, I’m completely stumped on this one… Can you help?
There is a sequence of pictures in the top row of this image. Which of the four options in the row below completes the sequence by filling the box labelled with a question mark?
Which of the four options should replace the question mark?
Hint:
The graph in each square represents an object. What might this object be, and how might the colours be important?
This is my own problem, with a well-defined solution. It is an inherently visual puzzle; the colours of the dots are listed in a pastebin. Note the precise details of the lines (length/straight vs. curved) and dots (precise coordinates, RGB values) are not required; some of the presentation is aesthetic.
