Extra Credit Journal

The following journal needs to be at least 200 words and is due on Januray 29th.


Geometric and Arithmetic Sequences:

Compare and contrast geometric and arithmetic sequences. (What do they have in common? How are they different?)

What is different about explicit and recursive formulas? Why do you think we write both? Is one more useful than the other? In what situation would it be best to use a recursive formula? In what situation would it be best to use an explicit formula?

Midterm Information

Midterm Setup:
Your midterm will be over the course of 2 days. Your grade will be a combined score over the two days. (Example if you received a 50% on the first day and a 100% on the second, your overall midterm grade would be a 75%). To study answer the questions in the review packet, review notes and past tests, and review the blog resources henryalgebra1.blogspot.com


Test Setup: Part 1 January 23rd and Part 2 January 24th
  • 30 multiple choice  (15 each day) questions worth 2 points each
  • 4 open ended questions (2 each day) worth 4 points each
  • 4 open ended questions (2 each day)worth 6 points points each
