Exc Think on Instagram: "To find the sum of the first 50 natural numbers (1 + 2 + 3 + ... + 50), we use the formula for an arithmetic series: Sn = n(n+1)/2 Step-by-Step Solution: Identify n: In this sequence, n = 50. Substitute into the formula: S_50 = 50(50+1)/2 S_n= 50(51)/2 Calculate: S_50 = 25 × 51 S_50 = 1275 The sum is 1275.
