In the circle-regions exploration, if a student follows the doubling conjecture $r = 2^{n-1}$ , what would be their predicted number of regions for $n=7$ dots?

Why is a table considered a useful representation for spotting changes in a pattern?

According to the textbook, what is one of the primary benefits of considering a 'more general case' first when solving mathematical problems?
