The sum of three consecutive odd integers is 231. what is the largest integer

These are really hard to think about, but start exploring.
So three consecutive odd integers, what does that mean?
1, 2, 3? Nope there's an even in there.
1, 5, 7? Nope you skipped 3 so it's not consecutive
1, 3, 5? Yes, you got it
Now what if we don't know the number? Let it be x!
x, x+2, x+4? I want you to see where I got these from:1, 1+2, 1+4.
Ok so the sum of these three odd integers is 231 let's do it

x + x+2 + x+4 = 231
3x+6 = 231
3x = 225
x=75.
If we plug back in into our unkown: x, x+2, x+4 we get:
75, 77, 79
The largest integer of these is 79.
Simple right? Let me know if you have questions.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
