loop

start with any (smallish) number at the top
  • go round the loop
  • what happens?
  • try other numbers
  • what happens?
  • always?
I wonder why that is...

try other starting places

try to justify what you have noticed using algebra, starting at the top (maybe 'm' for a million or 'n' for any number)

harder: try using algebra when you start somewhere else
