23
25
27
29

33
36

These numbers have something in common.
What is it ?

My wish is that no answer, hints, or comments of any kind to
this problem is posted here ...

... and further that no easy searching (by Bing, Google, etc.)
will ever lead to an answer.

Is that a challenge?

Maybe what I should've written is something like this: --

BEGIN>>>

If you know this answer,
Please, please, PLEASE wait at least 2 days before posting
the answer, link to the answer, hints, or comments,
or other spoilers.
Thank you.

<<<END

___________

P.S. --
a puzzle (by definition) has a short, simple answer.

So it may be tempting to post the answer immediately

( like a schoolchild who wants to be the
first one in his class to show that he
got the answer )

If he's excited enough (or immature enough),
he'll blurt out the answer to the whole class
without waiting for the teacher to call on him.

...in which case it's best not to post the problem here either. If a
puzzle is posted here, answers, hints, and comments are going to be
posted too. You'd have thunk henhanna would have learned that by now.

You chose the obvious search engine for the purpose, typed in the
obvious string, and it was the only hit, right?

For this problem
(Commonality in 21, 23, 25, 27, 29, . . . 113, 201)
I took more time & care in preparing, verifying, & presenting it,
(and there's no obvious mystery left in it for me)
So,
a smart-aleck (or an impudent teenager)
posting the answer within a few minutes
was a bit like being slapped in my face.

(Did he solve it?,
did he already know it?, or
did he just Google it?


On the other hand,
for the (Sultan dowry) problem
(CarTalk) Puzzler: Three Slips of Paper -- pick the largest number
https://en.wikipedia.org/wiki/Secretary_problem
I'd be fine with comments of any kind
because
I took almost no time in presenting it,
and there will always be obvious mysteries left in it for me,
including
--- what are some good strategies for the 4 numbers case?

I thought it was obvious from my post that I had
searched for it on the OEIS website in
response to your claim that finding the answer
by search engine was
impossible.

I did not post the actual answer and
anyone else who wishes to try and solve
the sequence by themselves is welcome
to do so.

(annoying isn't it?)

LOL!! Exactly why I have turned on the kill function to remove
needless rubbish. Thanks Peter!!
