Hi,
If you subtract consecutive terms, you see that you get:
You could find the quadratic. However, another way is to realize that

Hey guys! I haven't been online... here's a couple answers
Hi Ganesh,
Any new problems here? I'm up for some of these, as I need to hone my trig.
Hi ganesh
Hi,
I'm sorry if I'm posting these a bit late; I recently joined this site.
I heard somewhere in the 2050s, but I could be wrong. Imagine the slogan: "Immortality in a bottle." That would be something. However, even if it does become possible, there are certain ethical dilemmas that could be raised.
True, true. I dropped the E because I couldn't figure out a way to fit it in, but your way works perfectly bob.
Hi everyone,
I discovered this forum in a search for interesting logic puzzles and programming exercises; ever since then, I have meandered through each of the quirky sections and found many topics discussed that interest me and many people after my own heart. I have always loved solving that challenge math problem, writing that tricky program (like a word processor), cracking that seemingly impossible code, and this seems like a great place to talk with people that have similar interests. It probably is also a good place to start getting into topics that have previously eluded me, such as calculus, and hone my skills in areas that I already know, such as trigonometry.
By the way, I am going into ninth grade.
Here's a fairly simple code to crack:
Hydrogen Iodine. Holmium Tungsten Argon Yttrium Oxygen Uranium?
2011 is also the sum of three consecutive primes: 661, 673, and 677.
Furthermore, 2011= 39^2 + 17^2 + 7^2.
