flashcard patterns and relationships

Front

What is a pattern in mathematics?

Back

A pattern is a sequence of numbers or shapes that follow a specific rule or formula.

Front

What does it mean to 'divide by 2' in a pattern?

Back

Dividing by 2 means to take a number and split it into two equal parts, effectively reducing it by half.

Front

If a pattern starts with 40 and the rule is to divide by 2, what are the first five numbers?

Back

40, 20, 10, 5, 2.5.

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

How do you find the 3rd ordered pair in a pattern?

Back

To find the 3rd ordered pair, follow the pattern's rule starting from the first pair until you reach the third.

Front

What does it mean when we say 'the number of slices is 4 times the number of oranges'?

Back

It means for every orange, there are 4 slices, so if you have 2 oranges, you will have 8 slices.

Front

What is the rule for the pattern if the first number is 7 and we multiply by 2?

Back

The rule is to take the previous number and multiply it by 2 to get the next number.

Front

What are the first five numbers in the pattern starting with 7 and multiplying by 2?

Back

7, 14, 28, 56, 112.

Front

What is a missing number in a pattern?

Back

A missing number is a number that should be in the sequence but is not shown, often found by following the pattern's rule.

Front

How do you determine the missing numbers in a table of patterns?

Back

To find missing numbers, identify the rule of the pattern and apply it to find the numbers that fit.
