Answer:
-20, -19
Step-by-step explanation:
The average of the two numbers is -39/2 = -19.5. The smaller number is 0.5 less than this, -20, and the larger number is 0.5 more than -19.5, so is -19.

<em>Comment on the problem and solution</em>
I find that working consecutive integer problems is often simplified by working with the average value of those integers:
- the average of two consecutive odd integers is the even integer between them
- the average of two consecutive even integers is the odd integer between them
- the average of an odd number of integers of the same type (consecutive, consecutive odd, consecutive even) is the middle one
- The average of an even number of consecutive integers is the "half" number between the middle two (as in this problem).
None of those answers are right because the actual answer is 1.
Add 17 and 12 which equals 29. (17+12=29)
We already know there is 30 students so you just subtract 30 and 39 which equals 1. (30-29=1)
