This unit is about Arithmetic and Geometric series and sequences. By the end of this unit you should be ale to
Determine if a sequence is arithmetic or geometric
Find missing terms in these sequences using formulas or logic
Find the common ratio or difference of a sequence
Find the sum of a sequence
Find the first term of a sequence if missing
In this lesson your goal is to understand what is an arithmetic sequence and how to find a missing term in that sequence.
If you can solve these questions these questions then you have mastered the video.
In this lesson your goal is to understand what a geometric sequence is and how to use the geometric sequence formula to find a missing term.
If you can solve this questions these questions then you have mastered the video.
For the sequence 8, 4, 2, …
Find the common ratio.
Find the general term.
What is the 5th term?
What is u15?
In this lesson your goal is to be given an arithmetic sequence and be able to find the sum of that sequence using the series formula.
If you can solve this question then you have a good understanding of the video.
