More or Less, the BBC’s maths and statistics radio show, has been sneakily doing a puzzle on us for the last few weeks. The episodes in the series so far have each been ‘brought to you’, Sesame Street-style, by a different number. But what will the final episode be? Can you crack the integer code and solve the puzzle?
The puzzle was announced in the programme broadcast on the 27th of September; you can listen to it on the Radio 4 site or as a podcast (the puzzle bit is at 27:05). If you think you’ve solved the riddle, email More or Less through their website.
The episodes so far have been brought to you by the numbers 1, 49, 100, 784 and 1444. (It’s not in the OEIS; we’ve checked). You can find out if you’re right when the final episode in the series goes out, on BBC Radio 4 at 4.30pm on Friday 4th October.
