He can't have, I just tried it and got nothing except calendars! C'mon then, please explain to us mathematically challenged types how it works.... My brain's red hot right now and I'm seeing number sequences in my tea...

Yup. When I was in the lower sixth at grammar school, I had a mathematics teacher (Mr. Budden) who gave the class that problem. I was one of two who was able to solve it. I've never forgotten it and Ka Ora! is the only other person who could solve it all these years later, although I've set it myself for several very bright people.

Again, well done.

All the numbers in the series are the same, 16. The series is actually in the base number used, starting at base 16 (hex) and decreasing by steps of one towards binary.

We looked it up on the Integer Series website and learnt more of it. I got Lol to explain Base 16 to me (handy as he is a maths teacher!) and then had a fun evening of inventing series, only to discover they were already invented

Well done to Ka Ora! Very quickly spotted!

The only reason other than Computing that i recognised the sequence was it had a familiarity with an army encryption system I used a why back.

Jeez. Is this going to be an "its-a-small-world" moment? The other guy who found the solution way back then qualified as an MD, then joined up and ended in Army Intelligence. Alex, is that you??
