1. Consecutive Number Equations
Lesson 7-2

2. Math Vocabulary
consecutive: in order; one after the other

3. Finding Consecutive Integers
The sum of three consecutive integers is 96. 1st integer = n 2nd integer = n + 1 3rd integer = n + 2 Equation: n + (n + 1) + (n + 2) = 96

4. Finding Consecutive Integers
BUT…
You MUST name the integers by plugging n back into each integer equation!
1st integer =
n = 31
2nd integer =
= 32
3rd integer =
= 33

5. Finding Consecutive Integers
Find four consecutive integers with a sum of st integer = n 2nd integer = n + 1 3rd integer = n + 2 4th integer = n + 3 Equation: n + (n + 1) + (n + 2) + (n + 3) = 358

6. Finding Consecutive Integers
Find two consecutive EVEN integers whose sum is 66. 1st integer = n 2nd integer = n + 2 Equation: n + (n + 2) = 66

7. Practice Write & solve an equation for…
Two consecutive integers with a sum of 33
Four consecutive EVEN integers whose sum is -92
