Finding Consecutive Numbers
In this lesson, you will learn how to find three consecutive numbers that add up to a given sum. First, determine what the question is asking and identify that three consecutive numbers are needed. Next, represent these numbers with variables and write an equation that equates their sum to the given value. Simplify the equation and solve for the variable, which will give you the first of the three consecutive numbers. Finally, use the consecutive nature of the numbers to determine the other two and write out all three values.
Find three consecutive numbers whose sum is 138
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
