How to Solve Consecutive Number Problems Part 3

This is the third part of the Solving Consecutive Number Problems Series. In this post, we solve more problems about consecutive numbers. We have already discussed four problems in the first part and second part of this series, so we start with the fifth example.

Example 5

There are 3 consecutive odd numbers. Twice the smallest number is one more than the largest. What are the numbers?

Solution

In the first post in this series, we have learned that odd numbers increase by 3 (e.g. 7, 9, and 11). So, let

$x$ = the smallest odd number

$x + 2$ = the second odd number

$x + 4$ = the largest odd number. Continue Reading

How to Solve Number Word Problems Part 3

This is the third part of The Number Word Problem Series. In this post, we will be solving number word problems about consecutive numbers.  In number word problem solving, consecutive numbers are numbers that follow each other in order.  Here are the examples of consecutive numbers (integers).

consecutive numbers: 4, 5, 6, 7, 8, …

consecutive odd numbers: -2, 0, 2, 4, …

consecutive odd numbers: 7, 9, 11, 13, 15, …

I am quite sure that you have solved consecutive numbers in your high school mathematics class.

In the previous post, we finished our 6th problem, so, we start with the seventh problem. Continue Reading
