Lesson Transcript
Instructor: T.J. Hoogsteen

T.J. is currently a grade 5 teacher and Vice-Principal. He has a master's degree in Educational Administration and is working toward an Ed.D. in Educational Leadership.

When numbers are in counting order, they are also in consecutive order. This lesson will review the three different types of consecutive numbers (counting order, even, and odd),

What Are Consecutive Numbers?

Jeff and Omar were sitting around and talking about great sports teams. Jeff's friend brought up the New York Yankees dynasty from the late 1990s. He said that the Yankees won the World Series for three consecutive years starting in 1998. Omar, knowing the first World Series was won in 1998, tried to think of the years that the other two titles were won.

How could he figure that out? First, he would have to figure out what the consecutive numbers are that come after 1998. To do that, knowing what consecutive means would help. Consecutive means to follow continuously in a series or sequence. So that means consecutive numbers are numbers that follow each other in order.

Another thing to think about when solving the above problem is that there are three different kinds of consecutive numbers: consecutive numbers, even consecutive numbers, and odd consecutive numbers.

Consecutive Numbers

Consecutive numbers are numbers that follow each other in order from smallest to largest, what we call regular counting order. Let's take a look at some examples:

You can see that in each of these three series, the numbers go up by one each time, in sequence and without skipping any numbers in between. They are all series of consecutive numbers.

Even consecutive numbers are even numbers that follow in order from smallest to largest when you are counting by twos. Some examples of even consecutive numbers include:
