The sum of infinite, i.e. To simplify things, let’s use 1 as the initial term of the geometric sequence and 2 for the ratio. In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms. What is the probability of 53 Mondays in a year? The sum of an arithmetic progression from a given starting value to the nth term can be calculated by the formula:Sum(s,n) = n x (s + (s + d x (n - 1))) / 2where n is the index of the n-th term, s is the value at the starting value, and d is the constant difference. A sum of series, a.k.a. a = First number of the sequence. a 1 is the first term of the sequence, n is the number of terms, d is the common difference, S n is the sum of the first n terms of the sequence. Now you have to multiply both od the sides by (1-r): S * (1-r) = (1-r) * (a₁ + a₁r + a₁r² + … + a₁rᵐ⁻¹)S * (1-r) = a₁ + a₁r + … + a₁rᵐ⁻¹ – a₁r – a₁r² – … – a₁rᵐ = a₁ – a₁rᵐS = ∑ a∞ = a₁ – a₁rᵐ / (1-r).
