Final answer:
To find the exact sum of a series, you can apply a mathematical formula such as the formula for the sum of an arithmetic series or the formula for the sum of a geometric series. Alternatively, you can use a calculator or specialized series sum calculator for accurate results.
Step-by-step explanation:
To find the exact sum of a series, you can apply a mathematical formula. There are various formulas depending on the series. One common formula is the formula for the sum of an arithmetic series, which is given by (n/2)(first term + last term). Another formula is the formula for the sum of a geometric series, which is given by (a(1 - r^n))/(1 - r), where 'a' is the first term, 'r' is the common ratio, and 'n' is the number of terms.
Using a calculator or a specialized series sum calculator can also give you accurate results, but it's important to understand the underlying formulas to ensure the accuracy of the calculated sum.
