How to Use the SERIESSUM Function in Excel
Today, we’ll explore a powerful function known as SERIESSUM, which is available in both Microsoft Excel and Google Sheets. This function is particularly handy for handling complex calculations involving series. Let’s delve into its functionality and application!
Syntax
The syntax for the SERIESSUM function varies slightly between Excel and Google Sheets:
Microsoft Excel
SERIESSUM(x, n, m, coefficients)x: The input value for the series.n: The initial term of the series.m: The step value between terms in the series.coefficients: An array or a range that holds the coefficients used to multiply the terms in the series.
Google Sheets
SERIESSUM(x, n, m, coefficients, [k])k: An optional parameter that determines the number of terms to be included in the series. If not specified, all terms will be included.
Examples
To better understand how SERIESSUM can be utilized, let’s look at a few examples:
Example 1: Excel
Consider a series described by the formula:
\(3 + 6 + 9 + 12 + 15 + …\)
To calculate the sum of the first five terms using the SERIESSUM function:
| x | n | m | coefficients | Result |
|---|---|---|---|---|
| 1 | 3 | 3 | {1, 2, 3, 4, 5} | =SERIESSUM(1, 3, 3, {1,2,3,4,5}) |
The resultant sum of the first five terms is 45.
Example 2: Google Sheets
Let’s calculate the sum of the first four terms in the series defined by:
\(2 + 4 + 8 + 16 + 32 + …\)
In Google Sheets, you can specify the number of terms to include using the optional parameter k:
| x | n | m | coefficients | k | Result |
|---|---|---|---|---|---|
| 2 | 2 | 2 | {1, 2, 4, 8, 16} | 4 | =SERIESSUM(2, 2, 2, {1,2,4,8,16}, 4) |
The result for this example is 30, representing the sum of the first four terms.
As demonstrated, the SERIESSUM function is an essential tool for efficiently calculating sums in complex series in both Excel and Google Sheets. Feel free to experiment with various parameters and series configurations to fully utilize this function’s capabilities!
