Need Expert Advice on how to approach this type of question.

Post Thu Dec 06, 2012 11:26 pm
Q. What is the sum of a certain pair of consecutive odd integers?
(1) At least one of the integers is negative.
(2) At least one of the integers is positive.

Please help me on this one. I always get confused when terms such as 'At least' or 'at most' come in the question. How do I approach this type of question?

Thanks much!

Good question, ritind.

We cannot use the numbers {-3 -1 1 3 5 7} as one of our cases because the question tells us that we are dealing with a pair of integers (i.e., two integers).

Cheers,
Brent
