Find the sum of first positive 1000 integers.

Question

KnowledgeBoat · Accepted Answer

We need to find 1 + 2 + 3 + 4 + ...... + 1000 The above series is an A.P. with first term a = 1, d = 1 and n = 1000. By formula S_n = ⇒ S₁₀₀₀ = ⇒ S₁₀₀₀ = 500[2 + 999] ⇒ S₁₀₀₀ = 500 × 1001 ⇒ S₁₀₀₀ = 500500. Hence, the sum of first 1000 positive integers is 500500.
