Limits (or limiting values) are values that a function may approach (but not actually reach) as the argument of the function approaches some given value. The function is usually not defined for that particular value of the argument.
It may also be zero. This is because of the way the absolute value is defined. The idea is, precisely, to get rid of the minus sign.
In an arithmetic series, each term is defined by a fixed value added to the previous term. This fixed value (common difference) may be positive or negative.In a geometric series, each term is defined as a fixed multiple of the previous term. This fixed value (common ratio) may be positive or negative.The common difference or common ratio can, technically, be zero but they result in pointless series.
The 1981 Proof set has a current value of $9.00 and issue price was $11.00 but check the "S" mint mark on all the coins, on most of the sets the mint mark is filled an does not appear well defined. If all coins have a sharp clear mint mark, value may be $300.00 or so.
