Lesson Summary:

In this lesson, we learn how to find three consecutive even integers whose sum equals a negative number. Consecutive means numbers right next to each other, and we're looking for even numbers. We start by making x represent the first even number, and then relate the rest of our unknowns to that one variable. We then use the sum to create an equation and solve for x, which gives us the first even number. By adding 2 and 4 to that number, we find that the three consecutive even numbers that add up to negative 114 are negative 40, negative 38, and negative 36.

Lesson Description:

Finding Three consecutive even integers that equal a negative number

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.
