Complete the series: Tokyo, London, Helsinki, _, Berlin.
Clues: 2020, 1944, 1940, ...., 1916
Answer: Tokyo (1940) was missing from this list of city locations for postponed or cancelled Olympic games. Easy enough with the years added as clues during the week, so a special mention to Andrew Knox, Rubbond International, Ohé en Laak, The Netherlands, for spotting this on Monday. Also on the podium were: David Mann, key account manager, SPC Rubber Compounding, UK; John Bowen, consultant, Bromsgrove, UK; Stephan Paischer, head of product management special products, Semperit AG Holding, Vienna, Austria; Well done to all and everyone else who had a go.
Using any combination of addition, subtraction, multiplication, division, see how close to 952 you can get using some or all of the following numbers:
3, 5, 25, 50, 75, 100. (The result has to be an integer, and the above numbers can only be used once in your calculation)
The closest anyone got was 953, as worked out by Andrew Knox, John Bowen and (as shown here) David Mann:
100/5 = 20
20 x 50 = 1000
1000 - 75 + 25 + 3 = 953
