Is the "What is the middle number?" Question too confusing?
Is the "What is the middle number?" Question too confusing?
During the registration there is a question "What is the middle Number?" Below it there is a line with "012345". After several failed attempts, the correct answer was 3. Can you please show me the logic?

Re: Confusing question in Registration Form
Let's see . . . "0" is not considered to be a number.
Numbers are only 1 thru 9 . . . . hence, in the sequence 12345 ... 3 is the middle number.
(basic algerbra or numerology)

It's based on the fact that bots won't likely try twice.

From 012345 I would have guessed 23 as the middle numbervrkalak wrote:Let's see . . . "0" is not considered to be a number.

Re: Confusing question in Registration Form
I would have guessed 1234 as the middle number If 0 is not a number what if the figures were 543210 or 560043 or 000000.thegrogfrog wrote:From 012345 I would have guessed 23 as the middle numbervrkalak wrote:Let's see . . . "0" is not considered to be a number.

Re: Confusing question in Registration Form
How is 0 not a number??? Or was the humor lost over the internet...
Re: Confusing question in Registration Form
You are kidding right? Here is a some similar questions I would like you to test your theory.vrkalak wrote:Let's see . . . "0" is not considered to be a number.

Q1. On a soccer field, there are 6 players lined up. Their jersey numbers are 0, 1, 2, 3, 4, 5.
Give the middle player.
Q2. On a soccer field, there is only ONE player. The jersey number is 012345, give the middle number.
Q3. A code bar is "00045000", give the middle number.
I can admit I am not a genius in maths, although I think I am above average. But I really didn't get the logic of the original question in the registration form. If it was a trick to get you read and answer to defeat bot then it's OK. I was just wondering what was the idea.
EDIT: and nobody came up with another possible solution? The middle of 12345 = 12345 / 2 = 6172.5

Re: Confusing question in Registration Form
As I said, it's not meant to be answered right on the first try, which is what makes it so effective.

Re: Confusing question in Registration Form
At least it didn't say, "What is the standard deviation of these numbers..."

confusing quetion
within registration process:
i obtained:
after firstly confusing how to set 2.5 or 2,5 i.e. with which delimiterwhat is a middle number of (0 1 2 3 4 5)
i obtained:
F*ck!Nubber should be not less 3

Re: Is the "What is the middle number?" Question too confusing?
It violates logic. The median is definitely not 3.

0+1+2+3+4+5=15
15/6=2.5
2.5 rounds to 3.
It seems pretty easy for me - and it requires human intelligence. Besides, as already stated, a human will try more times, whereas a bot probably won't.

Because let’s face it, the unfortunate aspect of software development is that it involves humans. Mewling, disorganized, miserably analog humans. Sometimes they smell bad.
Re: Is the "What is the middle number?" Question too confusing?
Correct. To work out the median: there are six numbers so (6+1)/2 = 3.5, so the median is the 3.5th number ?edbarx wrote:It violates logic. The median is definitely not 3.
There is no median.
0 is a number. Sums of numbers are always numbers; 1 - 1 = 0. 0 isn't 0.9999* nor 0.1111* it has a definite value and is considered a number.

Re: Is the "What is the middle number?" Question too confusing?
The question is what's the middle number. And 3 is the closest as I proved above.Raffles10 wrote:That isn't the median it's the mean.
