 Arithmetic progression

An arithmetic progression is a sequence $a,a+r,\dots ,a+(m-1)r$ with constant successive difference $r$. It is nonconstant when $r\ne 0$.

An arithmetic progression (AP) is a sequence of numbers in which the difference between consecutive terms is constant. This constant difference is referred to as the "common difference." The general form of an arithmetic progression can be expressed as: - The first term is \( a \). - The common difference is \( d \).
