Section Checklist:
- Are you comfortable with different terminologies in this section?
- What is term? sequence? and series?
- Can you find the common different (d) using common difference formula?
- Can you find the nth term of a sequence using sequence formula?
- Can you find the sum of the first nth term of the sequence using the series formula?
- Can you use a sigma notation to describe sums of arithmetic sequences?
Section Contents:
A: Sequence
A sequence is a set of things (usually numbers) that are in order.
Each number in the sequence is called a term (or sometimes "element" or "member"). Also, when the sequence goes on forever (with the three dots), it is called an infinite sequence,otherwise it is a finite sequence.
B: Arithmetic sequences
An arithmetic sequence is a sequence whose terms go up or down by constant steps. (there is a common difference between terms).
C: Arithmetic series
D: Sigma Notation
