Write the explicit formula for the arithmetic sequence:

-3, -33, -63, -93, ...

• a_n = -3 - 30(n -1)

• a_n = -3 + 30(n -1)

• a_n = -30 - 3(n -1)

• a_n = -30 + 3(n -1)

Given the sequence:

25, 21, 17, 13,...

Write the explicit equation that models the sequence. (Hint: Simplify your equation by distributing)

• a_n = 4n + 29

• a_n = -4n + 25

• a_n = -4n + 29

• a_n = 4n + 25

Create the explicit formula for the sequence:

2, 8, 14, ...

(Hint: Write your formula and then simplify it by distributing)

• a_n=2+6n

• a_n=-6+6n

• a_n=6n-4

• a_n=4-6n
