Hallo If we specify a particular method for mapping the natural numbers to the rationals, could we also specify a "distance" between two consecutive terms in some general way? Also, are we able to calculate the nth term in such a progression, perhaps incorporating this distance function somehow within its expression?

See https://en.wikipedia.org/wiki/Pairing_function for example.
