Question 223562: Hi, I don't know how to do consecutive odd/even integers.
Such as this problem:

Find three consecutive integers whose sum is 36.

I know it's x+(x+2)+(x+3). Am I right? After all, they are 'consecutive', they are not odd or even.

Then the other one is:

Find two consecutive even integers whose sum is 126.

I did the first one, x+x+2=126
Then I subtracted two from both sides, and got x+x=124. Then I added like terms and got 2x=124. And then I simply divided by 2. And got 62.
I did the last question from another guy who answered another guy. But he didn't explain HOW to get the other one. I know the other answer is 64...but I do not know how to get it!
Please explain it clearly as I have an Algebra Test tomorrow, and I want to ace it.

Thanks. :)
