A summation equation is a mathematical expression that represents the sum of a sequence of terms, typically defined by an index. The summation notation uses the Greek letter sigma (Σ) to denote the sum. The general form of a summation equation is: \\\[ \\sum_\{i=a\}^\{b\} f(i) \\\] Where: - \\( \\sum \\) is the summation symbol. - \\( i \\) is the index of summation.
