An arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant and is calling common difference. The behavior of the arithmetic progression depends on the common difference . If the common difference is:
Positive, the members (terms) will grow towards positive infinity.
Negative, the members (terms) will grow towards negative infinity.
|an||Nth term of the sequence (dimensionless)|
|a1||First term (dimensionless)|
|n||Number of terms (dimensionless)|
|d||Common difference (dimensionless)|
