Q. Given the sequence:
25, 21, 17, 13,...
Write the explicit equation that models the sequence.  (Hint:  Simplify your equation.)
an = 4n + 29
an = -4n + 25
an = -4n + 29
an = 4n + 25

Q. Create the explicit formula for the sequence:
2, 8, 14, ...
(Hint:  Write your formula and then simplify it.)
an=2+6n
an=-6+6n
an=6n-4
an=4-6n

Q. Write a recursive rule for the sequence 17, 1, -15, -31 . . .
an = an-1 + 16
an = an-1 - 17
an = an-1 - 15
an = an-1 - 16

Q. Write the recursive formula for the following sequence?
6, 4, 2, 0, . . .
an = -2n + 8
a=6, an = an - 1 - 2
a1 = 6, an = an-1 + 2
a1 = 6, an = an-1 - 2
