Help with a riddle.

It's one of those stupiud figure out the missing number things.

81, 63, 27, __, 09, 81...

My logic is that every number is divisible by 3, and since the first number, wen divided by 3, equals the 3rd number, which in turn equals the fifth number, the second number divided by 3 gives us the missing number, which is 21.
Am I right?

81/3=27
27/3=09
63/3=21

I guess you were right.

Riddle me this....


I make you weak at the worst of all times. I keep you safe, I keep you fine. I make your hands sweat and your heart grow cold but seldom the bold. What am I?

Fear.

A cute innocent girl? >=O

how old are you, 14?

I don't think a 14y/o could supply me with a high-res Jessia Elwood piece I had been looking for for ages.

It's summertime, cut me some slack. ._.

It's not like I do math all break or something, I'm rusty. <.<

Second try.
The difference between 81 and 63 is 18. The difference between 63 and 27 is 36. 18 is the flip of 81, and 36 is the flip of 63. Now, the difference of 27 and 72 would be 45. The difference of 45 and 54 is 9. So, there we have the answer as 45, but how does 9 turn into 81? If I put a 0 before the 9, the difference between 90 and 9 is 81.

So, is it 45

if this is some sort of riddle instead of some math problem then read what I wrote if not your answer could be the one... >>

well there are actually tons of answers...

I have a "logic" subject in college so here's what I found out >>

if my answer is based on patterns instead of number divisibility or any other mathematical answers (though I did some little math but you get the idea), mine is 72... why?


phew... ok that' that... hoped I helped... your answer could be the one but there are still some details missing.

Oh, forgot about the last step. Thanks. ^^

I never expected to be learning math on a hentai site.

You could have also just noticed that they all added up to "9", then guessed that the answer was 45 or 54. :|

So is Fear the answer or what?

I never was, am always to be,
No one ever saw me, nor ever will,
And yet I am the confidence of all,
To live and breathe on this terrestrial ball.

What am I?

HINT: the first line is the most important.

PROTIP: THIS ISNT MATH, THIS IS SPOTTING PATTERNS IN WHICH THIS CASE HAPPENS TO HAVE AN ULTRA GAY PATTERN

1000 0001 = 0x81
0110 0011 = 0x63
0010 0111 = 0x27
.... ....
1000 0001 = 0x81

Too bad it is 6. If it were 4, it will be perfect to answer that the answer is 0x1F

Tomorrow.

Unless there's more information than you've given, I agree with Azul. I'm thinking there could be a more formulaic, or whatever, solution, but I'm too drunk to figure it out right now.

...The second coming of Jesus?

Seriously though, yeah, tommorrow.
