Prime sum of three term arithmetic progression?Here is a problem I found on brilliant.org Code:Select[Table[1+q^2+q^4,{q,1,Floor[Sqrt[1000]]}],PrimeQ[#]&]//Length but I am suspecting there is a better way to do it. Does anyone know of a better and/or shorter way to do it?

Re: Prime sum of three term arithmetic progression?Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130501 05:42:49
Re: Prime sum of three term arithmetic progression?I haven't noticed that at all. I was focused on finding an M only solution.

Re: Prime sum of three term arithmetic progression?Nope, CSBFC. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Prime sum of three term arithmetic progression?That is what I wrote, but the forum tirns it lower case automatically. What does that acronym mean?

Re: Prime sum of three term arithmetic progression?Sound like a good name for a book.

Re: Prime sum of three term arithmetic progression?Not a book, a dynamite article though. In mathematics, you don't understand things. You just get used to them.

Re: Prime sum of three term arithmetic progression?Sure. Why not!

Re: Prime sum of three term arithmetic progression?It already happened and I was the only person who read it. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #13 20130502 04:44:04
Re: Prime sum of three term arithmetic progression?The only mention of that article on the Internet is on this forum by you. I am guessing you are the guy who never got it published?

Re: Prime sum of three term arithmetic progression?Hmmmm, it appears you did not read everything I said about that article. In mathematics, you don't understand things. You just get used to them.

Re: Prime sum of three term arithmetic progression?Yes, I did.

Re: Prime sum of three term arithmetic progression?
We have already established in the other thread that though I may look brilliant and smell brilliant, I am not brilliant, In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #17 20130502 04:57:33
Re: Prime sum of three term arithmetic progression?We established exactly the opposite.

Re: Prime sum of three term arithmetic progression?I am afraid that it is difficult to establish assertions that are untrue. In mathematics, you don't understand things. You just get used to them.

Re: Prime sum of three term arithmetic progression?Is it the same answer if the fifth term is wrong? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #25 20130509 05:15:24
Re: Prime sum of three term arithmetic progression?Maybe and maybe not. Until he posts the correct fifth term we cannot know.
