Hi Jo  -  I don't have the answer but I do see some kind of pattern:

3+1=4, 6+4=10 gives 410

9+1=10, 6+2=8 gives 108

5+1=6, 4+8=12 gives 612

Hope this leads you to a solution  -  Good Luck!

Hi Jo, johnalex has given me an idea here - see what you think of this..
Take the odd numbers first and add them up - write this figure down. Then take the even numbers, add them up and write down this figure to the right of the previous figure. Works for all three - which would then make the other one....
7 + 5 + 3 = 15, 2 + 0 (ie 2 on its own as the only even number) = 2 hence   152
That works for me but pity that last number doesn't have two even and two odd numbers which would make it perfect. Anyhow, what do you think?

Biley,

Many thanks for suggestion.  It always seems to be the poser that falls at the fence.  I could see the logic though.  I am pulling my hair out!  I bet the answer will be so simple!  I tried looking at Ordnance Survey refs and then hoped to trace the town.  Then expected the answer to be the STD code minus the front 0!!!  Mad or what?!!  Obviously my idea was a non-starter.
