The answer cannot be A.
What if, in a, b, c --> b=c
Nowhere it is specified that the integers are distinct.
Also statement 2 says b>a, combining both we cannot say a,b,c are consecutive (eg 5,7,7) satisfies both statements but integers are not consecutive.

IMO E

don't know how it is A

1)we know about a and c not suff
2)b>a not suff

1+2
if a=1, c=3 and b can be 2 or 4 or any number greater than 1.

IF condition in question was given a<b<c then answer would be A

so E.

The question says "There are 3 integers, a, b, and c in that order", which means that a, b and c are all different and in that order would mean a<b<c. So statement 1 will be sufficient to answer the question as c=a+2 and as c>b>a, b should be = a+1.
Statement 2 is redundant statement and repeats what is given in the question.

P.S. Don't forget to give Kudos. :)

I concur with E. But my Doubt is what it means by "in that order" is it a<b<c? -- If thats the case, then C is the answer.

'In that order' means c>b>a
Statement 2 is redundent as it is already given in the question that c>b>a. So statement 2 is not required.

In that order does not mean that the integers are distinct.
{2,3,3,3,4,8,8,9} are in order(ascending) but this does not mean that 2 integers cannot be same.
a, b, c are in order can mean ascending as well as descending order.
So you cannot say that in order always mean ascending order.
Stem 1 says that c-a = 2 which justifies that the order is ascending and that's it. It does not mean that 2 integers cannot be same.

We can surely debate on the wordings of the question. But, to me it looks like the question is hinting for 3 different integers a,b and c rather than just any 3 integers. Taking that into account, I would go for A.

There are 3 integers, a, b, and cin that order. Are these integers consecutive?
1) a=c-2
2) b>a



The question says : a b and c are in the order : c >b > a

a = c-2 , says a is 2 less than c and which means b = c-1 , hence the 3 are consecutive. thus A is sufficient and this holds good for the numbers being +ve or -ve or combination of both

B : b > a , already understood from the question step

Kudos if the explanation helped

We can modify the original condition and the question. In order for integers to be consecutive, they need to be a, b(=a+1), c(=a+2). Hence, the difference between c and a needs to be 2. Thus, the answer is yes for the condition 1). The correct answer is A.

- Forget conventional ways of solving math questions. In DS, Variable approach is the easiest and quickest way to find the answer without actually solving the problem. Remember equal number of variables and independent equations ensures a solution.

When integers are in the question, you cannot assume that they are in the order. If they are in the order as written, then you need:
1) the quesiton that mentions "order"
2) or the quesiton that has a diagram showing it

(case1) there are 3 integers <== this is not in order
(case2) 3 integers are in that order <== this is in order
(case 3) when there is a diagram showing the order <== this is in order

Bunuel, VeritasKarishma can you help?
if the question is saying "in that order"
does it ABOSOLUTELY mean that:
a<b<c {ie. 1,2,3}; OR,
is it possible that another order could be
a=b<c {ie. 1,1,2} ?

I don't know what the question means. I would assume it to mean a < b < c but stmnt 2 makes no sense then.
An official question will specify "a, b, c in increasing order".

This question is part of paid adaptive tests and looks like this is is more of a Critical Reasoning question. GMAT generally gives clear question in test and does not confuses like this.
