4) create a simple drawing of three or more similar objects whose lengths can be represented by an arithmetical sequence. make the tallest figure 2 inches, then each successive picture ½ inch smaller. you may draw a simple picture or use a simple figure from clip art. 5) write the corresponding arithmetical sequence representing the lengths of the figures you drew. 6) for the sequence you found in question #5: a. what is a1? b. what is the common difference d? c. write an explicit formula for an using the formula for arithmetical sequences an = a1 + (n – 1)d.
