Consecutive Integers Sum: Example 1

Sum of Consecutive Integers: Example 1

A common word problem says that the sum of three consecutive numbers equals some given value. You are then asked to find the three numbers. Set this problem up by assigning a variable to just the first unknown number, for example “x”. Then the second and third unknown numbers can be expressed as x+1 and x+2 respectively. Then set up an equation that represents the sum and solve for x.
