When
the terms of an arithmetic sequence are summed, the result is an arithmetic
series. When the terms of a geometric sequence are summed, the
result is a geometric series. For example, the arithmetic sequence 1, 2, 3, 4,
5 is the basis for the arithmetic series 1 + 2 + 3 + 4 + 5. If
the terms of the geometric sequence are
added, the result is a geometric series, .
This section addresses two types of series: Arithmetic and
geometric. We provide examples with the explanation based on the
staircase model and area model.
