Question

prove sum of n natural numbers =n(n+1)/2​

Answer 1

Step-by-step explanation:

n(n +1)/2 i.e., the sum of the first n natural numbers is n(n + 1)/2. Prove by the principle of mathematical induction: ... + n = n(n +1)/2 i.e., the sum of the first n natural numbers is n(n + 1)/2.

Answer 2

Answer:

Good morning

+ n = n(n +1)/2 i.e., the sum of the first n natural numbers is n(n + 1)/2. Prove by the principle of mathematical induction: 1 + 2 + 3 + … + n = n(n +1)/2 i.e., the sum of the first n natural numbers is n(n + 1)/2.
