Reminding you that we have a quiz this Wednesday on:
- Arithmetic & Geometric Sequences
- Explicit and Recursive Definitions
Skills required:
- Finding the next term of a sequence
- Finding the nth term
- Understanding sequences as discrete functions
- Finding explicit (function) definitions given a few terms of a sequence
- Finding recursive definitions given a few terms of a sequence
Blog Prompt:
Review your notes 1st, otherwise you won't get much out of this.
Then respond to the following:
- What questions do you have on this topic?
- What mistakes are you most likely to make? (Since no one has earned a 100% on all of the quizzes, I expect thoughtful answers from all of you)
- Create a potential quiz problem on one of these topics. You will benefit most if you make this question on the topic for which you feel the least prepared. Add your solution, or attempted solution, as a comment so that others may compare their thoughts with yours. (If I get some good questions, then I will likely use some of them on the quiz)
Complete this assignment as soon as possible! The seniors and your classmates are waiting to help you but time runs out on Tuesday night.

1. What is the exact formula for the recursive/explicit equation? I know that it is better if I don't memorize the formulas, but they help me with the logic.
2. I have difficulties when trying to figure out the number of jumps. When is it one less? I like the hint to draw it out, so that will surely help me.
3. -3,1,5,9,...
Write the formula and the whether it is a geometric or arithmetic sequence. Also find the next four numbers to the sequence.
Answers:
y=4x+b
-3=4(1)+b
b=-7
Tn=4n-7
T(5)=4(5)-7
T(5)=13
T(6)=4(6)-7
T(6)=17
T(7)=4(7)-7
T(7)=21
T(8)=4(8)-7
T(8)=25
PS...This is supposed the be a comment, right?
