If possible, use at least three strategies to solve each of the following problems. At least two of your strategies should be visual strategies. Notice that a visual strategy involves matching each term of your Orcw attached response to a component of the figure. Consider the following sequence of pattern block figures. Figure 1 Figure 2 Figure 3 a) If we use toothpicks to build each figure, how many toothpicks do we need to construct the nth figure? If possible, represent your response as an expression and relate each term of your expression to a component of the nth figure.

If possible, represent your response as an expression and relate each term of your expression to a component of the nth figure.
