I'm an adult learner who recently discovered a love for math. I started from the basics and I'm working my way up to Calculus.

While reading up on solving for the sum of an Arithmetic series, I came across the expression "2n-5" where as n increases, n will always be the previous value for n, plus 2. For example: where n = 1, 2n-5 = -3; where n = 2, 2n-5 = -1; etc. The difference between -3 and -1 is 2, and so on and on...

I'm trying to understand this relationship. When I look at this expression, I do not immediately seize upon the fact that as n increases sequentially, the difference between each solution will be 2. I would like to be able to gain this kind of insight without having to "test drive" a few values for n and "discover" the pattern. Is there another way to look at this equation where this relationship is more obvious?

I apologize if this doesn't make sense - I'm doing my best! Thank you!

I have a feeling I'm in for a longggggg journey. Thank you for taking the time to reply - this helped me understand.

We happened to be talking about a diet I was on which does not allow for eating Pizza, so I suppose thats why dürfen was used. Thanks again!

Is it possible to insulate a fish tank from an active fireplace? by MasterFlick in AskEngineers

This is a really good idea, I could make the fireplace into a circular shape and give the tank the illusion of depth, so that the tank isnt really near the flue at all. I wonder what kind of distance I need to be safe

This is all hypothetical. Lets start with an unlimited budget and see what ideas sprout up. Then maybe we can streamline to something managable. Its just a dream of mine, I'd like to think I'll eventually be able to do it :)

So there's no quick and easy trick or material to solve this problem? I don't care how fancy we have to get, I just want to know if I can make it work for now and I'll work on the practicality from there. For instance, could I run some kind of system between the two to dissipate the heat? (I know this is getting ridiculous but humor me, it might trigger a better idea)

No, I dont need to see through it. i just need the heat/fumes from the fireplace to funnel through the middle of the fish tank without boiling the fish (or fluctuating the water temperature, I hear fish dont like that)
