Consecutive Even Integer Problems




 

In this lesson, we will learn how to solve algebra word problems that involve consecutive even integers.

Consecutive integer problems are word problems that involve consecutive integers.

What are consecutive integers?

Consecutive integers are integers that follow in sequence, each number being 1 more than the previous number, represented by n, n +1, n + 2, n + 3, ..., where n is any integer.

For example: 23, 24, 25, …

What are consecutive even integers?

If we start with an even number and each number in the sequence is 2 more than the previous number then we will get consecutive even integers.

For example: 16,18, 20, …

What are consecutive odd integers?

If we start with an odd number and each number in the sequence is 2 more than the previous number then we will get consecutive odd integers.

For example: 33, 35, 37, …

We will now look at some examples of consecutive even integer problems.

How to solve Consecutive Even Integer Word Problems?

Example : Consecutive Even Integer

John has a board that is 3 feet long. He plans to use it to make 4 shelves whose lengths are to be a series of consecutive even numbers. How long should each shelf be in inches?

Solution:

Step 1: Being consecutive even numbers we need to add 2 to the previous number.

Assign variables :

Let x = length of first shelf
x + 2 = length of second shelf
x + 4 = length of third shelf
x + 6 = length of fourth shelf

Step 2: Convert 3 feet to inches

3 × 12 = 36

Step 3: Sum of the 4 shelves is 36

x + x + 2 + x + 4 + x + 6 = 36

Combine like terms

4x + 12 = 36

Isolate variable x

4x = 36 – 12
4x = 24
x = 6

Step 3: Check your answer

6 + 6 + 2 + 6 + 4 + 6 + 6 = 36

The lengths of the shelves should be 6, 8, 10 and 12.

Answer: The lengths of the shelves in inches should be 6, 8, 10 and 12.
