Although the requirements of the syllabus are mainly arithmetic sequences and geometric series, due to the diversity of series, some non-arithmetic and non-geometric series of summation often appear in the test, so the students should master systematically Summation of columns. The following describes the common sequence of summation methods and techniques for your reference. First, the formula method The so-called formula method is based on known sequence summation formula, such as arithmetic difference
