Thank you Neil,
Here's my answrrs!!
then we do not know if it is an interesting puzzle
or a waste of time.
What tests have you done?
Can you guarantee it is a good problem?

who sent them in?
how did they get the numbers?
The last puzzle like this was not very clever.
something like. (fwded NS)
48 36
32 18
4x8=32
3x6=18, ...
it counted down and came to a dead stop at the next term.
I'll resend the questions that should be asked.!
They sometimes need more artificial silliness than

seqfans, gerard o, moderator,
someone recently posted
subject : A0 ??? etc.
body: what is the meaning of [a certain sequence id.] A0...??
[He?] did not give any terms or description or seq author?
everyone shivers, Was that one of my poor sequences?
Mumbles: well I can barely remember my phone number.
And ignores.
(please moderator-- can they ask for more info.)
another mathematician posted
subject: a/b+ b/c + c/a=n.
table.
d e f n.
== == == ==.
[without saying what d e f meant.]
I urge there should be a recap of relation of d e f to a b c n.
another mathematician (RG) posted something like
'interesting question' and quoted the entire article
without any interpretation.
another mathematician (perhaps pre yk) asked:
is
333333333333333333whatever prime?
[He?] did not easily state where the mixed digits came from.
21st cyclotomic polynomial whatever??
A formula such as 37!+1 or similar (factorial) could have been
a convenient shorthand formula.
or c*a^b+n.
Because, I have tackled world record primes (year 1987)
in multiply-exponent form.
4*Worlds largest known prime+3 has divisors 7, 6199, 92219.
What is (Sir Arthur) Eddington number. [1930s/
space mission? 21st Century.]
Claimed the number of protons in the Universe.
In shorthand equals identically
17*2^259.
(I factorised printout in Guinness Book of Records 1991?)
(Can be constructed with Euclidean tools. compass and straight edge.)
