1 says A+C is 2B
Insufficient since A B and C can be non integers too
2 says A B and C are integers
Insufficient
But 1 and 2 together gives ABC as consecutive integers with B as the middle number.

St 1: C-B = A-B. Hence A = C. therefore they are not consecutive integers. ANSWER
St 2: INSUFFICIENT as no further data has been provided

Option A

Statement (1) is => C-B = A-B

=> C = A - B + B = A

i.e. C = A.

Hence A, B, and C are not consecutive integers as A & C are same.

Answer - Option A

1. rewrite it as C-B+B=A or C=A - we know for SURE that A,B,C are not consecutive. moreover, we don't care if they are integers or not - we definitely know that A=C, and in this case, there is no way for them to be consecutive integers.
2. doesn't tell us much

VERITAS PREP OFFICIAL SOLUTION:

Solution: A

Statement (2) is insufficient on its own, as it allows for the integers to be spread across the entire number line; INSUFFICIENT.

If we add B to both sides of statement (1), however, we learn that C = A. If C = A, the integers cannot be consecutive, as at least two of them equal each other; SUFFICIENT, (A).
