I'm happy to respond.
I'm curious about the source of this question. I have never seen an official question that used the terminology "natural number." I believe the GMAT would always say "a positive integer." This question may have been written by someone who knew more about mathematics than he knew about the subtleties of the GMAT Quant section. If x is a positive integer, the lowest value would be x = 1, because 0 is not included in the natural numbers. That's a technicality the GMAT would not expect students to know.
If x = 1, then the expression equals -14. Answer = (B).
Does all this make sense?

Hey Mike.
Interesting Quote.
This isn't an official question. Hence i didn't specify the source.
But thanks for the input.
Lesson Learnt=> Wont reference Natural number again.
Infact i am changing the wording the wording here.
