Question

Find three consecutive even integers who's sum is 342

Answer 1

three consecutive even integers can be written

n,n+2,n+4

write the equation that adds those up = 342

then you can work out n

Answer 2

I would do \(\displaystyle \color{black}{ (n-2)+n+(n+2)=342}\)

Answer 3

yes, it's same (I'm not saying it's not).
That is just a way of thinking that you can divide by 3 to find the middle number.

Answer 4

Let's see if @Tevin will contribute to the solution.....
