5.OA.3 Patterns and Relationships

Front

What is a pattern in mathematics?

Back

A pattern is a repeated or predictable sequence of numbers or shapes.

Front

What does it mean to find a rule in a number sequence?

Back

Finding a rule means identifying the operation (like addition or subtraction) that connects the numbers in the sequence.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written as (x, y).

Front

What is the rule for the sequence: 50, 45, 40, 35, 30?

Back

Subtract 5.

Front

What is the rule for going from a number in the X column to a corresponding number in the Y column if Y = 2X?

Back

Multiply by 2.

Front

Which of the following is NOT an ordered pair from the table: (5, 10), (15, 30), (18, 30), (20, 40)?

Back

(18, 30) is NOT an ordered pair.

Front

What is the missing number in the sequence: 5, 7, __, 10?

Back

6.

Front

If you continue the sequence for both X and Y, what would be the next ordered pair after (20, 40)?

Back

(25, 50).

Front

What is the difference between a sequence and a series?

Back

A sequence is a list of numbers in a specific order, while a series is the sum of the terms of a sequence.

Front

What does it mean to 'continue a sequence'?

Back

To continue a sequence means to extend it by following the established pattern or rule.
