6-148.

Could you write an expression to find the number of dots in a figure?

Look at Figure 2 to the right where 4 groups of 2 dots are circled, and there is one dot left over. An expression representing the number of dots in this figure would be 1 + 4*x*, where *x* is the figure number. Use this to help you draw the next figures.
