Yes
No
10, 20, 30, 40, ...
Given the sequence:
25, 21, 17, 13,...
Write the general term that models the sequence.
an = 4n + 29
an = -4n + 25
an = -4n + 29
an = 4n + 25
Given the sequence:
25, 21, 17, 13,...
Write the general term that models the sequence. (Hint: Simplify your equation.)
an = 4n + 29
an = -4n + 25
