Given the following sequence: 3,9,27,81 Is this sequence

would the series of the sequence above be

what does the ellipsis ( ... ) mean at the end of a sequence?

What is the difference between a sequence and a series

She only briefly touched on the topic of the sigma, and we have gone over that in class. the bottom number and top number work the same way as the sequence notation above.

Match the numbers to the vocab

Is the series above

John is on the 3rd floor. He presses the elevator button, then climbs the stairs and presses the elevator button on the 4th floor, he goes up the stairs, presses the elevator button again, and does this for every floor until he gets to the 10th floor and presses the button there. How many elevator buttons does he press?

There is one flight of stairs between each floor. How many flights of stairs does John climb?

The difference in these questions is called a fence rail/fence post problem.

if you put in post 1, then 2 then 3 until you get to 25, then you have put in 25 posts. if you put in post 26 the next day, then 27, ... to 34, then you have put in 34-26+1.

if you are then putting in the number of fence rails between the posts, the first day there are 25-1 spaces that need rails. the second day there are 34-27 spaces.

when you write that n goes from 5 to 12, how many terms do you have in your sequence? is it a fence post or a fence rail problem?
