    Study Notes

    Series

    • A series is the sum of the terms of a sequence, which can be either finite or infinite.

    Finite Series

    • The sum of the first n terms of a sequence is denoted as S_n.
    • S_n is calculated by adding the first n terms: T_1 + T_2 + T_3 + … + T_n.

    Infinite Series

    • An infinite series sums infinitely many terms of a sequence.
    • The sum of an infinite series is denoted as S_∞.

    Sigma Notation

    • Sigma notation is a concise way to represent the sum of terms in a sequence.
    • The summation symbol Σ (Greek letter S) is used to denote the sum.
    • The general form of sigma notation is: ∑{i=m}^{n} T_i = T_m + T{m+1} + … + T_{n-1} + T_n.

    Sigma Notation Components

    • i is the index of summation.
    • m is the lower bound (starting index).
    • n is the upper bound (ending index).
    • T_i is the term of the sequence at index i.
