A series is a set of numbers, terms, or expressions that are added together in a specific order.
To find the sum of a series, you need to add all the terms in the series together. The sum can be calculated using a formula or by adding the terms manually.
The formula for finding the sum of a series is S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term in the series.
An arithmetic series is a series where each term is obtained by adding a constant number to the previous term, while a geometric series is a series where each term is obtained by multiplying the previous term by a constant number.
A series is convergent if the sum of its terms approaches a finite number as the number of terms increases, and divergent if the sum approaches infinity or does not have a definite value. The convergence or divergence of a series can be determined by applying mathematical tests such as the ratio test or the integral test.
