That's right, it's just the first few prime numbers creatively grouped and spaced. Your turn...

How did you work out what the grouping was?

From the answer, it seems to be interpreting the string of digits as a pair of two digit numbers, then a pair of three, pair of four, etc..

The grouping wasn't important, I'd have accepted other answers such as 192, 329, it was spotting that they were prime numbers that mattered.

I did consider those two answers, but decided than an ascending sequence was more appropriate. The numbers given up to that point had all been ascending integers, so 192 may not have been appropriate as it is less than 317. At least, that was my logic. I did go to and fro on it.

Anyway, some more mathematics. Please give the answer to the following - I expect it to be in the same format.

(Uddingston to Mollinsburn) + (Gildersome to Rothwell) / (Sunbury on Thames to Southampton) - (West Bromwich to Exminster)

As a hint - order of operations are important.

It is indeed correct. Your floor.

ADDENDUM: In case anyone was wondering, each route in brackets refers to a numbered UK motorway (with origin and destination as outlined on Wikipedia). Input the numbers into the sum and you get a number of another motorway.

I'll try to think of a question for later, but it's open floor for now.

Okay, here goes: which organisation was founded on 4th October 1883, and by whom and where?

I was a Scout myself but two of my Cousins were in the Boys Brigade founded by Sir William Alexander Smith, in Glasgow.
