Describe the pattern that you see. In your description, include the shapes that create the pattern. You can also mention colors. What is the first term (how does the pattern start)? How does the pattern change with each term? What would the next term in the sequence (pattern) be?

Picture 1 has 5 green squares.  It is one square with a square coming out from each corner.  Picture 2 adds an additional square extending out from each corner square, making a total of 9 squares.  This pattern continues, adding 4 green squares total each time.  This means Picture 3 has 13 squares, Picture 4 has 17 squares, and Picture 5 will have 21 green squares.
