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.
