Teaching Outlines

1. In different number pattern relating terms of the pattern
2. Defining different number pattern
3. Recognition of each terms
4. Differnce between finite and infinite sequence
5. Difference between sequence and series

Concept #1 Introduction to progression

Learning objectives

1. Identifying the pattern present in different number pattern
2. Meaning of the sequence
3. Defining the terms of the sequence
4. Writing the next terms and n'th term of the given sequences
5. Defining the finite and infinite sequence and examples.

Notes for teachers

1. An orderly arrangement of numbers according to a certain rule is called a sequence.
2. A sequence containing finite number of terms is called a finite sequence.
3. A sequence containing infinite number of terms is called an finite sequence.
