Fibonacci sequences | Statistics | Ian Mikardo | Readers in RomfordI was surprised to read that note Flinn’s letter (12 March) was dismissive of Fibonacci sequences. I find the basic sequence 1,1, 2, and 3,5, 8 very useful when driving abroad. I convert a distance in kilometres to miles by moving back one place in the sequence, and eg 8km becomes 5 miles. For more complex conversions like 11km,exhaust the 3 and the 8 and then add their predecessors 2 and 5 to get 7 miles. These conversions are surprisingly accurate.
