WebThe Greek letter Σ is a mathematical symbol for finding the sum of the first n terms of a sequence ak. The symbol Σ is the capital Greek letter sigma and is shorthand for ‘sum’. The lower and upper limits of the summation tells us which term to start with and which term to end with, respectively. For example, using the sequence an =2 n -1 ... WebAlternating positive and negative terms are common in summation notation. One way to represent this is by multiplying the terms by (-1)^i or (-1)^ (i+1) (where i is the summation index). To represent your example in summation notation, we can use i* (-1)^ (i+1) where the summation index is in the range [1, 10].
