Hi;


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

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?
