Sum of arithmetic formula
WebThe formula for the nth term of an arithmetic sequence is a_n = a_1 + (n-1)d, where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and d is the common … WebThe sum of infinite for an arithmetic series is undefined since the sum of terms leads to ±∞. The sum to infinity for a geometric series is also undefined when r > 1. If r < 1, the sum to infinity of a geometric series can be calculated. Thus, the sum of infinite series is given by the formula: S ∞ = a 1 − r Or lim n → ∞ S n = S ∞ = a 1 − r
