I know the answer, challege is for the mathematicans who monitor Yahoo questions :^)

Facetiously, this is not a math sequence!

Good luck.

I'm sitting in my apartment bedroom here in South East Ohio (Smack Dab in the Appalachian Hills) looking out my window right now, and I've always noticed after a hard rain the hills always start to ''smoke''. I'm guessing its steam, but where does it come from? It only happens after a hard rain too. Can water evaporate that quickly? If so, why that fast? No dumb answers please.

I am in New York City and tomorrow (January 6th) it's going to be near 70 degrees! That's just insane. While I love warm weather, I do find it really scary that it's this warm. I'm concerned about global warming and the effect it's going to have on us. I know I have a wild imagination but is it possible things will eventually get so hot we won't be able to survive here anymore? And how far off until scientists predict things to get really bad?
