Consider the following pattern of square figures. When discussed in class, we found 1 square in the 1st figure, 5 squares in the 2nd figure, and 14 squares in the 3rd figure. Fig. 1 Fig. 2 Fig. 3 Fig. 4
1 square 5 squares 14 squares ?? squares
The extra credit is broken into three parts. You may do any or all of them.
1) How many squares are there in figures 4 and 5?
2) Based on the pattern, how many squares would there be in figure 10?
3) Can you describe how the pattern works?
