(a) Graph the first 10 terms of the arithmetic sequence an = 2 + 3n.
(b) Graph the equation of the line y = 3x + 2.
(c) Discuss any differences between the graph of an = 2 + 3n and the graph of y = 3x + 2.
(d) Compare the slope of the line in part (b) with the common difference of the sequence in part (a). What can you conclude about the slope of a line and the common difference of an arithmetic sequence?
