mikemcgarry this makes complete sense, but can't a consecutive series of integers also be something like 2,4,6,8 and 3,5,7,9? That's why I was a bit confused because then statement 1 "could" be true. Obviously from the answer choices all three cannot be all true. the And I believe this question is from a kaplan bank. Thanks again.
Dear
cgalan6,
I'm happy to respond.
My friend, when any GMAT Quant question talks about "
consecutive integers" without adding any other qualification, it
ALWAYS means integers that differ by exactly 1 from each of their neighbors—e.g. {32, 33, 34, 35, 36, 37, 38}.
Yes, it's true that the test may also ask about
-
consecutive even integer, e.g. {-8, -6, -4, -2}
-
consecutive odd integers, e.g. {3, 5, 7, 9}
-
consecutive multiples of 3, e.g. {-6, -3, 0, 3, 6, 9, 12, 15} etc.
The test may ask about any of those, but it will
NEVER just say "
consecutive integers" and mean one of those sets.
My friend, precision is the very soul of mathematics, and all mathematical logic depends on precision. On the GMAT Quant, this mathematical precision extends to the words: every single word used in every single prompt on the GMAT Quant is used with extraordinary precision. What I have explained here is the precise meaning of the term "
consecutive integers."
Does all this make sense?
Mike
