Re: Number in the series

Hi picon;

If you pair the numbers off you see that each pair sums to 23. The first number appears to be going up by 2 so I think the next 2 are 18 and 5.

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
