Which of the following is not an arithmetic sequence?

1,2,3,4,5,

2,4,8,16,32,

15,9,3,-3,-9

answer:

i think the answer is

1.create another line that intersects the segment.

this is because, when ever everyone writes when they want to do another part they draw a line threw the middle of the page and write under it.

everyone might not do that, but most people i know do.
