Identifying Linear Sequences

The video tutorial explains how Natalie identifies whether a sequence of numbers follows a consistent pattern. It involves checking the difference between each pair of numbers to determine if the sequence is linear. If the differences are constant, the sequence is linear, and the constant difference is noted. The tutorial uses a number line to illustrate the calculation of differences, confirming the sequence's linearity with a constant difference of seven.

What is Natalie trying to determine about the sequence of numbers?

• If the sequence follows a consistent pattern

• If the sequence is increasing

• If the sequence contains only positive numbers

• If the sequence is decreasing

What is the first step in identifying if the sequence is linear?

• Check if the numbers are in descending order

• Check if the numbers are in ascending order

• Check the difference between each pair of numbers

• Check if all numbers are positive

How is the transition from -2 to 5 visualized?

• Using a graph

• Using a chart

• Using a number line

• Using a table

What is the difference between the first two numbers in the sequence?

• 8

• 5

• 7

• 6

What is the constant difference found in the sequence?

• 7

• 6

• 8

• 5

What conclusion is drawn about the sequence?

• It is linear with a constant difference of 8

• It is linear with a constant difference of 5

• It is not linear

• It is linear with a constant difference of 7

What should be selected if the sequence is linear?

• Select 'not linear' and the constant difference

• Select 'not linear'

• Select 'linear' and the constant difference

• Select 'linear' without a constant difference
