If a sequence A = {a1, a2, a3, ... } is an arithmetic progression then the sequence H = {1/a1, 1/a2, 1/a3, ... } is a harmonic progression.
It is a progression of terms whose reciprocals form an arithmetic progression.
harmonic series 1/n .
It is a sequence of numbers. That is all. The sequence could be arithmetic, geometric, harmonic, exponential or be defined by a rule that does not fit into any of these categories. It could even be random.
phrase
Such a sequence is called a quint.
It is called a term.Each number in a sequence is called a term.
They are called terms in a sequence.

This is called a sequence and if we add the numbers in that sequence it is called a series.
