Find the explicit formula for this 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)

Select the explicit rule that represents the sequence.

•  $a_n=6\ +\ 5\left(n\ -\ 1\right)$ 

•  $a_n=5\ +\ 6\left(n\ -\ 1\right)$  

•  $a_n=6\left(5\right)^{\left(n-1\right)}$  

•  $a_n=5\left(6\right)^{\left(n-1\right)}$

Create the explicit formula for the sequence:

2, 8, 14, ...

(Hint: Write your formula and then simplify it.)

• a_n = 2 + 6n

• a_n = -2 + 6(n - 1)

• a_n = 2 + 6(n - 1)

• a_n = 2 - 6n
