WebOct 6, 2024 · 2Sn = n(a1 + an) Dividing both sides by 2 leads us the formula for the n th partial sum of an arithmetic sequence17: Sn = n(a1 + an) 2. Use this formula to calculate the sum of the first 100 terms of the sequence defined by an = 2n − 1. Here a1 = 1 and a100 = 199. S100 = 100(a1 + a100) 2 = 100(1 + 199) 2 = 10, 000.
