The answer to last week's #PuzzleThursday is: A There is a sequence - box, circle, triangle - so that the next large (outside) figure must be a circle. Each large figure next becomes an inside figure, but shaded. Thus in the third figure the shaded small box becomes the large shaded square and the next in turn will be the shaded small circle, which in the fifth figure will be large.
Can you figure out what comes next in this week's #PuzzleThursday?
