1. ARITHMETIC SEQUENCE (ILLUSTRATING ARITHMETIC SEQUENCE) SIR MELCHOR M. DEL ROSARIO

2. LESSON OBJECTIVES Determine whether each sequence is arithmetic or not. Find the common difference and the next terms of an arithmetic sequence.

3. SHORT ACTIVITY Determine whether each given is a sequence or not. 2, 4, 6, 8, 10 4, 7, 8, -11, 53 1, 2, 5, 19, -4 1, -3, 9, -27, … 1, 1, 2, 3, 5, 8, … SEQUENCE NOT SEQUENCE NOT SEQUENCE SEQUENCE SEQUENCE

4. MATCH STICKS ACTIVITY Below are squares formed by match sticks. Count the number of matchsticks for each figure and record the results in the table. Number of Squares 1 2 3 4 5 6 7 8 9 10 Number of Matchsticks

5. ARITHMETIC SEQUENCE An arithmetic sequence is a type of sequence where every term is obtained by adding a constant number called the common difference (d) .

6. ACTIVITY 1: Determine whether each of the following is an arithmetic sequence or not. If the sequence is an arithmetic sequence, give the common difference and the next term.
