  limit of the nth partial sum does not exist,then we say the series diverges and has no sum. Convergence Tests We were able to determine that the geometric series converges by examining its nth partial sum. However, as it turns out,a formula for the nth partial sum of most infinite series cannot be found.

  The n-th 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. A series can have a sum only if the individual terms tend to zero. But there are some series

  The sequence (sn) is called a series in X and is written as P xk or P k xk. The n-th term sn of the sequence (sn) is called the nth partial sum and xk is called the kth summand of the series P k xk. Definition 6.1. The series P k xk converges or is convergent if the sequence (sn) of partial sums converges. The limit limn→∞ sn is called the ...

  The nth partial sum is Sn = 5 5 1 n+1 which converges to 4 as n gets larger and larger. The in nite cancellation gives 5, which is incorrect. The series in Examples 2, 3, and 4 are very special. Unfortunately, for most series there is no way to calculate a simple formula for the nth partial sum, S n.

  Think of series as a process of adding together the terms starting from the beginning. Then the nth partial sum of the series is simply the sum of the rst n terms of the series. For example, the partial sums of the Meg Ryan series 1 2 + 1 4 + 1 8 + are: 1st partial sum = 1 2 2nd partial sum = 1 2 + 1 4 = 3 4 3rd partial sum = 1 2 + 1 4 1 8 = 7 ...
