If you write the first digit of pi after one minute, then the second digit after 30 seconds, then the third after 15 seconds, then the fourth after 7.5 seconds, and so on...

What's the last number you've written after two minutes? Is it the last digit of pi?

Huh? There isn't a last number you've written after two minutes. You've written them all, but there's no terminating one.
