As one quantity increases an equally obvious opposite quantity decreases vs. there is only one obvious quantity, which increases as the sequence progresses right.

Another way of phrasing the solution: "Neither direction would more naturally be called increase in quantity vs. rightward progression would be called an increase."

Most right examples shown are unboundedly increasing, since finite sequences showing a quantity increasing usually also suggest "distance to end of sequence" as a decreasing opposite quantity. Even so, there are some finite sequences with one direction more intuitively increase-like than the other.

Quantities on the left are dual in the following sense: as one quantity increases an equally intuitive opposite quantity decreases.

Most right examples shown are unboundedly increasing; finite sequences showing a quantity increasing usually also show "distance to end of sequence" as a natural decreasing quantity. Even so, there are some finite sequences with one direction more intuitively increase-like than the other.

Quantities on the left are dual in the following sense: as one quantity increases an equally intuitive opposite quantity decreases.

Most right examples shown are unboundedly increasing; finite sequences with a quantity increasing usually also show "distance to end of sequence" as a somewhat natural decreasing quantity. Even so, there are some finite sequences with one direction more intuitively increase-like than the other.

Quantities on the left tend to be symmetrical in the following sense: as one quantity increases an equally intuitive opposite quantity decreases.

Most right examples shown are unboundedly increasing; finite sequences with a quantity increasing usually also show "distance to end of sequence" as a somewhat natural decreasing quantity. Even so, there are some finite sequences with one direction more intuitively increase-like than the other.

Quantities on the left are in a sense symmetrical; as one quantity increases an equally intuitive opposite quantity decreases.

Most right examples shown are unboundedly increasing; finite sequences with a quantity increasing usually also show "distance to end of sequence" as a somewhat natural decreasing quantity. Even so, there may be some finite sequences with one direction more intuitively increase-like than the other.

Either direction could be interpreted as increase in quantity vs. right direction is the increase.

Quantities on the left are in a sense "symmetrical"; as one quantity increases an equally intuitive opposite quantity decreases.

Most right examples shown are unboundedly increasing; finite sequences with a quantity increasing usually also show "distance to end of sequence" as a reasonably intuitive decreasing quantity. Still, there are some finite sequences with one direction more intuitively increase-like than the other.

Quantities on the left are in a sense "symmetrical"; as one quantity increases an equally intuitive opposite quantity decreases.

Quantities on the left are in an intuitive sense "symmetrical"; as one quantity increases another opposite quantity decreases.

Either direction could be interpreted as increase in quantity vs. right direction is clear increase.
