Graph the arithmetic sequence an = –4, –1, 2, 5, 8, …
a. What is the 8th term in the sequence?
a_ n = a_1 + (n – 1) d.
a_8 = -4 + 7(3) = 17
b. What is the recursive formula for this sequence?
A_n+1 = a_n + 3
c. What is the explicit formula for the nth term? How does this formula relate to the slope intercept form of a linear equation?
a_n = 3n - 7
d. What is a story or situation this pattern could represent?
