I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!
Leave your answer or, if you want to post a question of your own, send me an e-mail. Look in the about section to find my e-mail address. If it's new, I'll post it soon.
Please don't leave spam or 'Awesome blog, come visit mine' messages. I'll delete them soon after.
The answer is 2.
ReplyDeleteThere are two patterns:
2,3,4, etc. and 9, 18, 36, etc.
2 9 3 18 4 36 5 7(2)
So, did the title help you solve this? I couldn't really come up with a better title, even after trying for 15 minutes.
ReplyDeleteTo confirm, parrotgirl has it right. The next number in the sequence is 2.
Yes. It showed me that there were two patterns. However it took me forever to realize there were double digit numbers.
