eight, four...ten...?

The most obvious answer is 6 (as described above).\n\nBut here's another option...\n\nThe correct answer to "10" could be 2.\nIn the case of the password for "eight" being 4, it could be the number of letters in the word "eight" minue one (5-1=4).\nTherefore, the answer to "10" would be 3-1=2.

Hold up eight fingers.  Now put down three of them.  That leaves five of them.\n\nThe answer is 5.\n\nIt is also equivalent to the number of points you lost asking this question... but I guess you are just having fun with Yahoo! Answers coming up with silly questions, aren't you.  Enjoy!

Do you mean permutations?\n8P4\n= 8!/(8-4)!\n=8!/4!\n= 8*7*6*5\n= 1680

It is 4 because Five is 4 letters...  Like ten has 3 letters and three has 5 letters.

Could be 10,14,13. The odd terms differ by 3 (eg. 4-1,7-4), the even terms differ by 4.

Eight out of ten is a bit generous, don't you think? I'd shoot for nine out of ten...and I encourage all answeres to do us a favor and click the little button "Check Spelling" before replying to this post.

8 numbers can be placed  in 8! ways.\nExchange the three two's gives no new numbers, so divide by 3!\nExchange the two six's gives no new numbers, so divide by 2!\n8! / ( 3! x 2! ) = 1680\n\nTh
