Hi;


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Oral puzzles

Hi bobbym,

I made a mistake in the problem #1730.

The corrected problem 'How many terms are there is the following Arithmetic Progression

'?

#1731. How many terms are there in the Arithmetic Progression 7, 13, 19, ......, 205?
