Sneakattack Jul 23, 2011	This is my first brainteaser.
SUPD200 Jul 23, 2011	Nice brainteaser! I was thinking of subtracting 3 to each number, since when you subtract 3 to 1, you get -8, but I saw no negative sign.
DemonLord8 Jul 24, 2011	Nice teaser! I thought the pattern was -3 then +7.... 7-3=4 4-3=1 1+7=8 8-3=5 5-3=2
opalrose25 Jul 24, 2011	Great teaser but I didn't have a keyboard in front of me since I did it on my iPad
dancingrobots_ Jul 24, 2011	I did it as Seven has 5 letters. The next has 4 then 3. Then i started again at Eight with 5 letters. And so you would need another number with 3 letters, so i got TWO. Its a sequence of 5-4-3, 5-4-3.
Sneakattack Jul 25, 2011	Interesting observation dancingrobots
xdbtcp Jul 25, 2011	I got it right, but I was going 'up' on my phone instead of 'down' on the keyboard...
Kronos Jul 25, 2011	I got it the same way as Demon. Good job. Fun but easy.
Mandy7 Jul 27, 2011	y r u named kronos? u no thatz the name of the evil Titan lord in the Greek stories? ugh
lolia Jul 31, 2011	i got it right and yeh it was fun but easy
Brain1231994 Aug 01, 2011	I have a laptop (which means 0 key pad)
dishagarg Jun 07, 2012	mine ws a diff approach...dint any1 notice that the numbers in the series are those of the units place digits dat occur in the 7's table
rashad Oct 30, 2012	In another way : 7 - 3 = 4 4 - 3 = 1 Now just imagine the numbers from 0 to 9 as a chain circle, so 0-1=9 and 4 - 7 = 7. Then : 1 - 3 = 8 8 - 3 = 5 5 - 3 = 2
kitty-cat Feb 26, 2013	Well, I'm on a laptop. Got it anyway...thought about what a computer keyboard would look like.
spikethru4 Feb 26, 2013	On most keypads, 0 is directly below 1 (as a double-width key), so you could introduce 0 into the series to make it a little harder and throw off the mathematical reasoning. 7, 4, 1, 0, 8, 5, ...
