Learning Objective
At the end of the lesson, you will understand how to identify, represent, and predict terms in an arithmetic sequence.
Engage: Introduction to Sequences
Explore daily life examples of sequences, like calendar dates. Identify patterns and predict the next sequence.
Explore: Defining Arithmetic Sequence
An arithmetic sequence is a sequence of numbers where each term after the first is obtained by adding a constant, called the common difference.
Explain: Formula Derivation
The nth term of an arithmetic sequence is given by: a_n = a_1 + (n-1)d, where a_1 is the first term and d is the common difference.
Elaborate: Hands-on Activity
Calculate the 10th term of the sequence: 3, 7, 11, 15, ... using the formula.
What do you already know about number patterns and sequences?
Evaluate: Class Exercise
Given the sequence: 2, 5, 8, ..., find the 15th term. Check your understanding of the arithmetic sequence formula.
Extend: Real-World Application
Discuss how arithmetic sequences are used in financial planning, such as predicting savings growth over time.
