How Do You Use an Equation with Consecutive Numbers to Solve a Word Problem?
Note:
Word problems are a great way to see math in the real world. In this tutorial, you'll see how to translate a word problem into a mathematical equation involving consecutive numbers. Then you'll see how to solve that equation and check your answer!
Background Tutorials
-
Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
-
How Do You Evaluate an Algebraic Expression?
Plugging variables into an expression is essential for solving many algebra problems. See how to plug in variable values by watching this tutorial.
-
What is a Variable?
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
-
-
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
-
What are Like Terms?
Combining like terms together is a key part of simplifying mathematical expressions, so check out this tutorial to see how you can easily pick out like terms from an expression
-
-
Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).

Further Exploration
-
Solve real-world and mathematical problems leading to two linear equations in two variables.
-
How Do You Solve a Word Problem Using Two Equations?
Sometimes word problems describe a system of equations, two equations each with two unknowns. Solving word problems like this one aren't so bad if you know what to do. Check it out with this tutorial!
