Today we started talking about Arithmetic Sequences. I passed out two different handouts that you should come by my office and get if you were not in class today. One was a table for you to keep all of the equations for Sequences and Series together, and the other was your classwork/homework dealing with Arithmetic Sequences. The handout has a great example for you to reference as well as the equation. The only other term we discussed is the Common Difference. This is the difference between two numbers in a sequence. For example, in the sequence 2, 4, 6, 8 the common difference between each number would be 2. Common difference is designated by a "d" in the equation for arithmetic sequences.
Remember that you have a TEST tomorrow! The test will be cumulative!
Coming up:
- TEST tomorrow
- We will begin Arithmetic Series on Tuesday
- You will have a "midterm" test on October 17th
Posting for Points:
What is the "common difference"?

d- common difference
the difference between two numbers in an arithmetic series
it is the d in the formula and means the difference between two consecutive numbers in a sequence.
Common difference is the difference between two consecutive numbers in the sequence and is represented by D int he Arithmetic Series forumla.
difference between #'s
the common difference is the variable "d" in the equations that we have learned recently in class. it stands for the difference between two numbers in a sequence
the difference between 2 consecutive terms of an arithmetic progression
