Hi - I guess we can test cases.

A/ 3 consecutive integers be -1,0,1 or 0,1,2 so we get a YES and a NO
B/ If the sum of 3 consecutive integers is zero then the set must be symmetric so -1,0,1
So we a get a definite yes for this question so Sufficient.

Cheers

I need a suggestion on this one guys.

1 and 2 are not sufficient we can determine that by looking at it since either one misses out detail about one or the other one.

For together can we add the inequalities?

if we add the inequalities we get x-z<3 and now we know the range cannot be determined if it is less than 2.

Is this approach correct?

expert opinions please
