You know those tests where you get a series of numbers and have to find out the underlying rule.
Here’s one for traders: the rate of a certain currency follows a simple rule, without any random deviation. The rates of the last 12 days:
3, 6, 6, 8, 8, 7, 7, 9, 8, 8, 6, 9
If you can figure the rule, you know when to buy or sell and you’ll get obscenely rich. What’s the rates of the next 3 days? 
9, 11, 10 
It’s the number of letters in the name of the number in the list of integer numbers
one = 3, two = 3, three=4 etc…
Your sequence starts with ten.
ten=3, eleven=6, twelve=6, thirteen= 8 etc.
so the next in sequence would be
twentytwo=9, twentythree=11, twentyfour=10 etc.
9, 11, 10, 10, 9, 11, 11, 10, 6, 9, 9, 11, 10, 10, 9, 11, 11, 10, 5, 8, 8, 10, 9, 9, 8, 10, 10, 9, 5, 8, 8, 10, 9, 9, 8, 10, 10, 9, 5, 8, 8, 10, 9, 9, 8, 10, 10, 9, 7, 10, 10, 12, 11, 11, 10, 12, 12 etc. etc.
you just wanted us to do your homework for you didn’t you? 
Jeez… You guys gotta take the fun outta EVERYTHING… 
LMAO
Here’s one I read a long long time ago in a brain book that took me forever to figure out.
What number comes next?
15, 20, 20, 5, 5, 19, 19, 6…
When in doubt… add vodka.
With fresh pomegranate juice, a splash of club soda, and a lime wedge:D
Wow, I had not assumed that this puzzle would be solved so soon!
I had posted the same challenge on another big traders forum a week ago and no one there was able to solve it so far.
May be 25?
Forget that other forum. All the brains are on this forum.
6 .
While that would be the logical conclusion, it’s not the answer.
Ok, I’m not smart enough to solve this puzzle. Why would you post it on a forex forum?
