NOTE:

​

​WE WILL HAVE A POST TEST AFTER THIS LESSON SO BE SURE YOU HAVE UNDERSTOOD ALL BEFORE WE END THIS SESSION.

​

​YOU CAN GO BACK TO THIS LINK ANYTIME FOR A REVIEW. POST TEST WILL HAVE A DEADLINE FOR A FEW DAYS.

​WHAT WE NEED TO LEARN & UNDERSTAND TODAY:

​PART I. SEQUENCE

​1. What is a sequence?

​2. What are the elements of a sequence?

​3. What are the characteristics of a sequence?

​4. What are the types of sequences?

​5. What are the examples for each type of sequence.

What's your

next line?

Please write your answer here.

For you, what did Jolina say in the last part?

​Don't you know that what you did was

​putting something in order.

​By filling up what Jolina said, you were reading and

studying the previous conversations in order to fill up your

own version of appropriate response.

​

​This skill that you have shown is relevant and a necessity

​to our lesson involving SEQUENCE.

​1. So, what is a Sequence?

​Sequences involve patterns. 

​Identify the pattern is a key to recognizing the

​rule of order in sequences.

​

​If you are good at analyzing things,

​our lesson will be "SISIW" for you.

​

​

​We can also illustrate sequences thru pictures.

​For example, can you identify a pattern describe by the figures below?

​Let me know...

Here are my observations.

​Are they same as yours?

​

​What do you think is the next drawing for each sequence?

​2. What are the elements of a sequence?

​Question: Is there a last term?

​​3. What are the characteristics of a sequence?

​Can you classify each sequence below?

A FINITE sequence is definite and has a last term; but

​An INFINITE sequence goes on forever so there is no last term.

Other characteristics of a sequence.​

​4.What are the types of sequence?

​Common

difference?

​Common

​ratio!

​If you noticed, the denominators of a harmonic sequence consists of terms of an arithmetic sequence... 

​   6, 10, 14, 18, 22, 26, 30, 34, 38

​Harmonic sequence in nature

​The height of these sprouting

​plants demonstrate harmonic

sequence:

​Harmonic sequence are also demonstrated in music through the notes. The dots in the arm of a guitar is actually an harmonic division. That is why it is called "harmonic".

​There are many other types of sequence but we will have to concentrate on the 4 examples you have been shown. They are:

​

ARITHMETIC SEQUENCE

​GEOMETRIC SEQUENCE

FIBONACCI SEQUENCE and​

​HARMONIC SEQUENCE

​

Which sequence is easiest for you to identify?

Why? Please give a short explanation.

SHORT QUIZ​

Take note that you will be given a time limit to answer.​
