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.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
