How do you find the sum of a sequence?
To find the sum of an arithmetic sequence, start by identifying the first and last number in the sequence. Then, add those numbers together and divide the sum by 2. Finally, multiply that number by the total number of terms in the sequence to find the sum.
What is the sum of a series?
The nth partial sum of a series is the sum of the first n terms. The sequence of partial sums of a series sometimes tends to a real limit. If this happens, we say that this limit is the sum of the series. If not, we say that the series has no sum.
What is the sum of infinite series?
An infinite series has an infinite number of terms. The sum of the first n terms, Sn, is called a partial sum. If Sn tends to a limit as n tends to infinity, the limit is called the sum to infinity of the series.
