The sum of three consecutive odd integers is 207. What are the integers?
An odd number is 2n + 1
This odd number - 2 is also a odd number is 2n+1-2 = 2n-1
This odd number +2 is also a odd number is 2n+1+2 = 2n+3
Sum:
(2n−1)+(2n+1)+(2n+3)=2076n+3=207|:32n+1=69 This is the second odd number
The first integer is 69-2 = 67
The second integer is 69
The third integer is 69+2 = 71
Divide 207 by 3. Add 2 to your result. Then subtract 2 from your result. Those 3 answers are what you are looking for.
Try it out on your own. Learn a little :)
you should get sixty seven, sixty nine and seventy one.
