Yes yes, again I have a problem and I turn to this forum for help.
I'll crawl back into the luker shadows when this is solved.

Yesterday, the newspaper had a nice riddle:
We have the logic sequence 4,6,9,6,14,x.
Choose the correct x from 16, 17, 19 or 21.

The answer should be in today's paper, but I couldn't get my hands on it!

I sad down with 3 other beta-students yesterday trying to solve it. We failed...

So, do you guys have an idea?

It's not 16 is it?

4, 6, 9, 6, 14, 16, 19, 16

4 is 2/3 of 6. 6 is 2/3 of 9. That's as far as I can get.

We've thought of that. But we concluded that the given sequence is to small to determine this, and therefor it should not be the answer.


Yup.. we've thought of this too. Didn't bring us very far.

How is it to short to come to that conclusion? They give you the possible answers and that is the only one that fits (to me)

It's 21.

4,6,9,6,14,21,24,21

14 is 4*3.5
21 is 6*3.5

Well first, we can not fill in an answer, and than find the logic. (In other words, we should be able to find x without the given answers)
Second, it is only 1 number where they added 10, and we thought it would not be enough to prove that the sequence repeats itself adding 10 each repeat. It could just be coincidence. If it said 4,6,9,6,14,16,x than yes, than 19 could be a logic x.

Havent thought of that yet.
But I disagree.

It is again based on just 1 fact: 4 * 3.5 = 14.
Since "x = 16 because 4 + 10 = 14 and 6 + 16 = 16" is also based on just 1 fact, I think this proves that you need more than 1 fact to find what x is.

I'd be surprised if they used addition, but I guess it's unable to be proven. Do they reveal the answer in tomorrows newspaper?

They reveal it in today's. But I'm unable to get it.
Perhaps I can read it tomorrow, if it isnt trown out already.

I came up with 21 as an answer but it's not exactly perfect.

6 / 4 is 1.5. 9 / 6 is 1.5. 1.5 + 1.5 = 3.
6 / 9 is 0.6666. 14 / 9 is 2.3333. 0.6666 + 2.3333 = 3.

Now for the next part I'm assuming that the sequence of 1.5, 1.5, 0.6666, 2.3333 starts over.

21 / 14 is 1.5. 31.5 / 1.5 is 21. 1.5 + 1.5 = 3.

Actually the next logical step would be 0.3, 2.7 but those wouldn't give any numbers that are options as an answer. Unfortunately there's not enough numbers in the sequence to verify this.

A guy I just spoke came up with this:



number 1 + number 4 = 10
( 4 + 6 = 10)
number 2 + number 5 = 20
(6 + 14 = 20)
so number 3 + number 6 = 30

number 3 = 9, so number 6 should be 21.

Numbers :ahhh:

kidding

I'm guessing 17.

Are you sure there isn't a number missing?

A google search for your progression comes up with:

4 - 6 - 9 - 6 - 14 - 6

Which makes the solution rather easy.



Well thats my theory, and I'm sticking to it.

Yes. We know.
But this is exactly what the newspaper said.
Perhaps a missprint?

There is probably some logical way to arrive at all of them.

You got to be kidding me!
Number 5 was in the paper of the day before yesterday!
Big chance that number 2 was suppose to be in yesterday's paper... but they misprinted it.
