SERIESSUM

SERIESSUM 函數會計算和傳回次方數列的加總。係數是用於以階值遞增的 x 值連續次方。

SERIESSUM(x 值, 次方, 階值, 係數)

x 值： 次方數列的 x 輸入值。 x 值是數值。

次方： 代表 x 值的初始次方的數值。

階值： 數值，代表針對數列中的每項增加次方的階數。

係數： x 值的連續次方所依循的係數會被相乘。係數的數目會決定次方數列中的項數。係數為包含數值的集合。

附註

SERIESSUM 函數支援任意的開始點或指數間隔。如果不需要任一項，請考慮使用 POLYNOMIAL 函數。

較高的階項會較後表示。係數（a_i）是用於 x 值的連續次方。在下列公式中，「x」代表 x 值，「n」代表次方，而「m」代表階值。SERIESSUM 函數所使用的公式是：a₁ xⁿ + a₂ x^(n+m) + a₃ x^(n+2m) + ...+ a_k x^{(n + (k-1)m)}，其中 k 是係數的數字。

指數必須是非負值的整數。

範例

=SERIESSUM(2, 0, 1, 9) 會傳回 9。

=SERIESSUM(2, 0, 1, 1) 會傳回 1。
