5.18- Finding a Pattern Rule - One and Two Step In and Out Flashcard

Front

What is a pattern rule?

Back

A pattern rule is a rule that describes how a sequence of numbers or objects changes. It helps to predict the next number or object in the sequence.

Front

How do you find the next number in a pattern?

Back

To find the next number in a pattern, identify the rule that describes the pattern (e.g., adding, subtracting, multiplying) and apply it to the last number.

Front

What is an example of a one-step pattern?

Back

An example of a one-step pattern is: 2, 4, 6, 8. The rule is to add 2 to the previous number.

Front

What is an example of a two-step pattern?

Back

An example of a two-step pattern is: 1, 3, 6, 10. The rule is to add 2, then add 3 (1+2=3, 3+3=6, 6+4=10).

Front

What does 'in and out' mean in a pattern quiz?

Back

'In and out' refers to the input (in) and output (out) of a function or pattern, where you apply a rule to an input to get an output.

Front

If the input is 5 and the rule is to add 3, what is the output?

Back

The output is 8 (5 + 3 = 8).

Front

If the input is 10 and the rule is to multiply by 2, what is the output?

Back

The output is 20 (10 x 2 = 20).

Front

What is a sequence?

Back

A sequence is an ordered list of numbers that follow a specific pattern or rule.

Front

What is the difference between a one-step and a two-step pattern?

Back

A one-step pattern involves a single operation (like adding or subtracting), while a two-step pattern involves two operations (like adding then multiplying).

Front

How can you represent a pattern rule?

Back

A pattern rule can be represented using an equation or a function, such as y = 2x + 1.
