Select the following series as arithmetic, geometric, or neither. 1 + 2 + 3 + 4 + . . . + 10

Novosadov [1.4K]

The series is an arithmetic series.

The progression has a common difference of 1. You can tell because it involves a plus sign, which is indicative of an arithmetic progression,

A geometric progression would include multiplying the numbers by a certain amount. For example:
1, 3, 9, 27 ... 243
In this series, you multiply the numbers by three to get your answer.<span />
