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.
