Match the sequence with the given nth term with its graph. an = (-1)" an an 10 2- 8 1 ... 6. 4. 2 4 6. 8 10 -1+ -27. 4 6. 8 10 an an 0.6 10 0.4 0.2 8 -2 2 4.6 8 10 4. -0.4 -0.6 -0.8 -1.0 2 4 6 8 10

Which sequence is modeled by the graph below? 10 (4, 9) 8. 9. • (3, 3) 2 1. (2, 1) 3 4 8 9 10 O a, = -(27)n - 1 O a, = 27(-y-1 (3) -1 a. = 3(yn - 1

Given the arithmetic sequence of 4, 2, 0, -2, . .fund an explicit rule for the nth term. O an = an 1 2 O an = an 1+2 O an = 4 + (n – 1) (-2) O an = 4 + (n + 1) (-2)

-1, 5, -25, 125 ratio and the next the terms
