Question

The sum of first ‘n’ odd natural numbers is​

Answer 1

(n) square is the answer for question

Answer 2

Answer:

n²

Step-by-step explanation:

The first n odd natural numbers are given by 1,3,5,7,9…… (2n – 1) and this forms an AP.  

a = 1  

d = 2  

tn = (2n – 1)

The formula of sum of an A.P series

=>S = n/2[2a + (n − 1) × d]

=>S = n /2 [2 + 2n – 2]

=>S = n /2 [2n]

=>S = n²

The sum of first n odd natural numbers is n²
