Paradoxical Puzzles

This puzzle involves a time loop that goes on forever. You start at time 1, and for each number, you have to add 1 or subtract 1 to get to the next number. Sounds simple, but things get weird.

Here's the rules:

• For each number, add 1 or subtract 1 to get to the next number.
• You can only add or subtract 1, no more, no less.
• You can't go backwards, you can only go forwards.

Start at 1. What number do you get to?
