Hi Ganesh;

To (xliii) problem 68

I get n^3-n^2+n as the general term. So the next 2 terms are 301 and 456

hi Jane Fairfax

Cannot find the command to hide an answer.

So I'll follow a long tradition amongst mathematicians and make an anagram.

Is it dedelute ?

Hi Bob;

Use the hide tags:

hi JaneFairfax,

Whoops, yes I did.

What command do you use to hide things in boxes, please?

Hi JaneFairfax,

Thanks for the hide help. But I've still not fully grasped it. You can create a box which has a 'title' embedded in it.

eg.

but where do I put the hidden content?

Hi bobbym,

How are you today?

Thanks for the hide help. That sorts it out for me.

With regard to JaneFairfax's Liverpool question, I think she's set a tough one if you're in the USA.

Back in July you advised me "R. I. P. O. S. T. P."

So what happened to English soccer in the year ?

Even so, you're in for a lot of gooling.

Bob

Hi bob;

How are you today?

I'm alive.

Back in July you advised me "R. I. P. O. S. T. P."

Yes, I did.

I think she's set a tough one if you're in the USA.

And I surmised that. But I won't be taking my own advice.
