What is the sum of the arithmetic series
To find the sum of an arithmetic series, you can use the formula:
\[ S = \frac{n}{2} \left(2a + (n-1)d \right) \]
Where:
- \( S \) is the sum of the arithmetic series
- \( n \) is the number of terms in the series
- \( a \) is the first term in the series
- \( d \) is the common difference between consecutive terms
Using this formula, you can calculate the sum of the arithmetic series.
