How do you find two consecutive odd integers?

I'm not understanding the question. Two consecutive odd numbers will be of the form x and x+2. So simply pick the first one (hopefully you know what "odd" means and don't inadvertently pick an even number; if you're worried about this, then pick any integer at random, double it, and add one, the result is guaranteed to be odd) and add two to get the next odd number.


WHAT DOES ASSCIATIVE PROPERTY OF ADDITION?

By repeatedly applying the commutative and the associate properties, you can rearrange any set of numbers you need to add in any order.
