Solve the problem.How many line segments are determined by joining the dots on the last two circles?
3 segments6 segments
segments
segmentsLook for a pattern. How many line segments are determined by joining n dots on a circle? How many line segments are determined by joining 14 dots on a circle?
What will be an ideal response?
5 dots: 4 + 3 + 2 + 1 = 10 segments
7 dots: 6 + 5 + 4 + 3 + 2 + 1 = 21 segments
n dots : 
segments
14 dots: 91 segments
