	Decent quiz. However, you included a space before the answer in 8th problem, so if you type the answer, it does not work. Please fix that.

	Got all 10

	I'm not sure what your talking about podsednik, I checked to see if there were a space and there wasn't...I'm not sure what happened.

	Pit_trout:	Jun 16th, 2010 at 15:43 GMT		2 points
	About the 8th problem: maybe you need to check "accept single-character answers" in the quiz options? (As Podsednik says, it doesn't currently accept "9" unless you put a space before or after.) Nice quiz!

	sixtyseveners:	Jun 16th, 2010 at 16:13 GMT		3 points
	accept single character answers please. Could you add a third column that shows the sequence that generates the pattern?

	msingh3000:	Jun 16th, 2010 at 19:38 GMT		1 point
	Fixed that up sixtyseveners, and I purposely did not give up what the pattern is so their is some replay value. Figure it out :)

	Accept 0.2 for 1/5. Otherwise: pretty good, way too much time.

	msingh3000:	Jun 17th, 2010 at 04:47 GMT		2 points
	shortened the time, and put .2 for an acceptable answer for you wyvernsabres

	how do you get the next number in this pattern : 1,4, 27, 256...

	msingh3000:	Jun 17th, 2010 at 18:26 GMT		3 points
	1^1=1 2^2=4 3^3=9 4^4=256 5^5=?

	HandeltheMessiah:	Jun 19th, 2010 at 01:25 GMT		6 points
	Once I got past 2, 2, 4, 12, 48 it was easy. I still don't get the answer for that one, though; I just typed in the number that popped up when I clicked "Give up".

	The problem with this quiz is that there are uncountably infinite patterns that one can imagine that start with the given numbers, making this at best a guessing game.

	Handel- 22=4 43=12 124=48 485= ?

	wilsonhubbell:	Jun 21st, 2010 at 15:34 GMT		2 points
	Along with the answers, have the explanations for how to get the answers pop up along with it. For example, in the answer section of where you made your quiz you can type "3125 (1^1=1 2^2=4 3^3=9 4^4=256 5^5=?)/3125". Just an idea...

	msingh3000:	Jun 21st, 2010 at 17:48 GMT		0 points
	As I said before, I purposely didn't add the answers so there is incentive to play again...But if anybody has a question on an answer, I will reply to it the same day.

	wilsonhubbell:	Jun 21st, 2010 at 18:30 GMT		5 points
	I guess I am honestly confused. How does not giving away the answer to how the pattern works increase the replay value? It still gives the answer to the one you can't get. I would think understanding the pattern would make you want to play it again and feel good about moving on to the next one, whereas not understanding how it works but moving on anyway would be frustrating.

	msingh3000:	Jun 21st, 2010 at 21:53 GMT		-3 points
	So if I gave all the patterns away, there would be absolutely no reason to keep playing since there is no way to show only the one you were stuck on, but all of them, which is how I intended it to be in the first place.

	wilsonhubbell:	Jun 22nd, 2010 at 16:09 GMT		4 points
	This is not true. You can give the patterns away one by one if you follow my instructions above. no matter.

	msingh3000:	Jun 22nd, 2010 at 19:16 GMT		0 points
	If youur having that much trouble figuring it out, just let me know.

	canwetakearide:	Jun 25th, 2010 at 01:10 GMT		2 points
	damn, I was looking forward to the last one :P

	ppirilla:	Jun 25th, 2010 at 23:02 GMT		2 points
	the rest of them were pretty easy, but I still can't see (2,2,4,12,48) and (2,4,8,12,96). Also, (1,4,13,40,121) and (1,2,5,14,41) feel kinda redundant. Liked the last one, though.

	msingh3000:	Jun 26th, 2010 at 16:14 GMT		2 points
	21=2, 22=4, 43=12, 124=48, 485=?...soo n1,2,3,4... 42=8, 8+4=12, 128=96... so multiply first two, then add next two, then multiply, then add...

	Wilsonhubbell, I did not know that you could do what you wanted me to and I was being stubborn because of it. I took your advice and changed the game to how you suggested and I believe it is a lot better because of it.

	jackie_chan:	Jun 28th, 2010 at 02:19 GMT		1 point
	fun game...the second last one was really tricky

	wilsonhubbell:	Jun 28th, 2010 at 13:33 GMT		2 points
	well done! my extreme kudos to anyone who can admit they were confused. it does look better. make another.

	wilsonhubbell:	Jun 28th, 2010 at 13:36 GMT		3 points
	also "Add increasing odd number (3,5...)...36" is strange way to put this. to me it is just the series of perfect squares. both are true, i suppose.

	msingh3000:	Jun 28th, 2010 at 17:07 GMT		1 point
	Yeah I was having trouble explaining that one

	superfly:	Jun 29th, 2010 at 21:52 GMT		1 point
	For the second to last, I think it would be more accurate to say "Multiply by 3, then subtract by increasing multiples of 2." "2 to increasing powers" sounds like you are subtracting by 2, then 4, then 8, then 16, etc., which is not the case.

	msingh3000:	Jun 29th, 2010 at 23:00 GMT		1 point
	Thanks for that superfly, that was how i originally intended the pattern to be, but forgot and did it the other way. oops. but i changed it anyhow

	brickhaus77:	Jun 30th, 2010 at 19:04 GMT		1 point
	It still won't accept 0.2. I was stuck forever on that one until I tried 1/5.

	msingh3000:	Jun 30th, 2010 at 19:29 GMT		1 point
	It accepted .2, but I wasn't aware that it had to be that specific that 0.2 would not apply, because .2 is the same thing as 00000.2 or 0.2. However, I chanegd it for u
