Aug 27, 2020 at 7:38 | comment | added | PDT | No I was talking about the number 68 and not the solution | |
Aug 26, 2020 at 20:03 | comment | added | ThomasL | 68 is correct and the sequence is increasing, hence next two numbers are greater than 68, so 32 is wrong. | |
Aug 26, 2020 at 10:47 | comment | added | PDT | It seems like it should be 32 | |
Aug 26, 2020 at 10:23 | comment | added | PDT | Is that 68 correct | |
Aug 25, 2020 at 20:34 | comment | added | ThomasL | @msh210: thanks for your clarification. What you said at the end for the prime numbers is what I intended to ask. I added 'increasing' to the question, hopefully it helps and makes it more obvious. | |

Aug 25, 2020 at 20:20 | comment | added | msh210 | [continued] "Here's a set of numbers, which I've written the first few of in increasing order. Identify the property defining the set, and identify the next two". Then the answer would be "It's the set of primes". So I'm not sure what's going on in our present question. Is it a good question like my Fibonacci one above, or is it a question with a multipart answer whose parts have nothing to do with one another: (2 or more of) "increasing", "integer", and [something else]? I hope it's the former (but will find out when I find or see the answer). | |
Aug 25, 2020 at 20:17 | comment | added | msh210 | [continued] Then the answer is "The sequence is the set of primes, arranged in increasing order". You'd need to specify it's increasing -- and, more to the point, the question is a bad one, because the answer, "primes, increasing", has two properties that really have nothing to do with one another. It's like asking a sequence whose answer is "primes, that have an odd number of letters in their name" -- why is that interesting? why would any solver think of that? The answer should be cohesive and sensible. In the 2,3,5,7,11 case, a better question would be [continued] | |
Aug 25, 2020 at 20:14 | comment | added | msh210 | The point of my previous comment was this: The question doesn't say it's an increasing sequence of integers. So it's possible that that's part of the answer. For example, suppose we were asked "The sequence 0,1,1,2,3,5,8,... follows a certain property. Find the property and the next two numbers". Then the answer is "The sequence follows the property that each element after the first 2 is sum of the preceding 2. The next two numbers are 13 & 21". But suppose we were asked "The sequence 2,3,5,7,11,13,17,... follows a certain property. Find the property and the next two numbers". [continued] | |
Aug 25, 2020 at 19:24 | comment | added | Lukas Rotter | @msh210 Well spotted! It also seems to be vig("key", "xyklipc afsgf iss mel mvckxc lc ynhgxk mdlcb rswfcbw rykcdlcb") | |
Aug 25, 2020 at 19:23 | comment | added | WhatsUp | I hope someone post the old gag of a polynomial interpolating these values. | |
Aug 25, 2020 at 19:16 | comment | added | msh210 | Well, to start, it seems to be rot13(vagrtref, naq vapernfvat). | |
