In my geometry book I am really stumped on these question.This is what it says to do, "Find a pattern for each sequence. Use the pattern to show the next two terms."And here are th questions I am stuck on with the #'s.

7.O,T,T,F,F,S,S,E,...
8.J,F,M,A,M,...
13.George,John,Thomas,James,...
14.Martha,Abigail,Martha,Dolley,...
15.George,Thomas,Abe,Alexander,...
16.Aquarius,Pisces,Aries,Taurus,...
Please help if you can I am really confused on those, thank you. =)

But then what pattern is it? I thought there were simularitys such as #'s 7 and 8 being all letters but what is the pattern like what should come next?

I'm still thinking on #7 and 8, but the patterns in #13 and 15 are U.S. presidents, so I have to go look them up to find out the pattern

14 are presidential wives(i have to find the pattern)
I'll get back to you in a little while after I research

Okay thanks alot I am on independent study so it is not easy when you get stuck, I am going to do english now but I will check back here later.

# 7 -- Think numbers, one, two . . .

# 8 -- Think months
# 9 -- http://www.astrology-online.com/persn.htm

Ohhhhh so then next in the pattern would be E and the letter that is 14 letters away from E?

#7 is E, you're right

#8 is J (June)
#13 is James (James Monroe)
#14 is Elizabeth (Elizabeth Monroe)
I'll get back to you on 15 and 16

For these questions I need the next 2 answeres in the pattern though like for the last one OTTFFSSE I needed the next 2 which are NT for Nine and Ten.

#15 is Gemini

N,T is the next 2 in the pattern for #7, Sue helped by saying think numbers.

O,T,T,F,F,S,S,E=one two three four five six seven eight so the next two would be N and T Nine and Ten.

This site will help with # 13, as Brie indicated.

You can look up the First Ladies to find the pattern for number 14.

I'm stumped on 15.George,Thomas,Abe,Alexander,...
None of our presidents' first name was Alexander.
