Patterns

[Jessi]

Hi everyone! I was wondering if I could get some help with a few (probably simple) patterns we were assigned in class today. Had no problem with the others, but I got stuck on these...

4.) 1, 1/2, 1/4, 1/8...

6.) 81, 27, 9, 3...

7.)O, T, T, F, F, S, S, E...

For the first two, find what you're dividing by at each stage. For the last one, I'll give you a "hint", since this isn't a math puzzle:

One
Two
Three
Four

See the pattern?

...and you can find hints to 8), 9), and 10) on the other webiste.
