Waxing.
In the term "waning Moon", "waning" is derived from "wane", not from"wan". It means decreasing.
A decrease in the illuminated portion of the Moon is called waning. When the illuminated portion is increasing, it is called waxing.
It is called rate of change.
The answer is trend
Trend

That is called waning, the opposite of waxing.
An arithmetic sequence does not have a constant rate of increase or decrease between successive terms, so it cannot be called anything!The constant increase or decrease is called the common difference.
This phase is called a waning moon and occurs as the moon transitions from a full moon to a new moon. The decrease is a result of the changing position of the moon in relation to the sun and Earth.
the moon is getting smaller. waning means to increase so it makes sense.
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
