Sequences Series and Summation

Create the explicit formula for the sequence:
2, 8, 14, ...
(Hint:  Write your formula and then simplify it. Distribute and combine like terms.)

• a_n=2+6n

• a_n=-6+6n

• a_n=6n-4

• a_n=4-6n

Given the sequence:
 25, 21, 17, 13,...
Write the explicit equation that models the sequence.  (Hint: Simplify your equation. Distribute and combine like terms.)

• a_n = 4n + 29
