Understanding Sequences and Expressions

Miss Hernandez teaches how to translate between tables and algebraic expressions. The lesson covers writing expressions for missing values in tables, identifying patterns in sequences, and calculating areas of triangles using expressions. Students learn to apply algebraic concepts to solve problems involving age differences and geometric calculations.

What is the main focus of Chapter 2, Lesson 3?

• Learning about historical events

• Understanding geometric shapes

• Solving quadratic equations

• Translating between tables and expressions

What did the class already cover in Chapter 1?

• Geometric transformations

• Historical timelines

• Algebraic expressions

• Tables and sequences

What new concept is introduced in this lesson?

• Algebraic expressions

• Geometric shapes

• Historical analysis

• Chemical reactions

In Example 1, what is the common difference used to find the missing value?

• +4

• +5

• +2

• +3

In Example 1, if Spike's age is 10, how old is Rusty?

• 18

• 12

• 16

• 14

In Example 2, what is the pattern used to find the sequence?

• Subtraction of 3

• Addition of 5

• Multiplication by 7

• Division by 2

In Example 2, what is the expression for the sequence?

• 7/a

• a-7

• a+7

• 7a

In Example 3, what method is used to find the expression for the sequence?

• Graphical analysis

• Guess and check

• Direct calculation

• Trial and error

In Example 3, what is the correct expression for the sequence?

• 5n + 2

• 2n + 5

• 4n + 3

• 3n + 4

In Example 4, what is the expression for the sequence with position 1, 2, 3, 4?

• 3n + 3

• 2n + 4

• 4n + 1

• 5n + 2
