I have a conceptual question. Whenever the GMAC mentions consecutive integers, does the sequence necessarily have to be ascending? If not, do some properties change if one chooses the integers in a descending order?

consecutive numbers are always taken in ascending order. eg. n-1 , n , n+1 would be taken as consecutive integers.
Also, yes; 'some' properties would change if u choose the integers in decending order.
for example: For a set of 3 conecutive integers A,B and C.
C-A = 2
but
A-C <> 2
It may be disastourous while arriving at an answer.
On the other hand
B= (A+C)/2
and also
B= (C+A)/2
Therefore, you would always want to choose consecutive numbers in ascending order on GMAT.
Hope it helps.

Yes consecutive integers can be positive or negative.
1,2,3
or -3, -2, -1
And they are taken in ascending order. Consecutive integers beginning from -5 would be -5, -4, -3, etc...
