Exercise 95 Page 48

We are given a dot pattern.

Note that each pattern continues to increase by the same number of dots and in the same location for each figure. Because each new figure has 3 more dots than the previously figure, the Figure 4 will have 3 more dots than Figure 3.

The same will occur with Figure 5. We will add three dots to Figure 4 to get the sketch of Figure 5.

Finally, we will do the same for Figure 6.

Recall the pattern of the given figures.

Note that we can separate each figure into one left line and two parallel lines formed by the dots. In each figure, we added 3 points. One point is added in the left line and the other two parallel lines grow by one dot each time. These is the way the pattern is changing each time.
