to verify the sum of first n natural odd numbers is n2

Answer 1

To verify that sum of first n natural odd numbers in $n^{2}$
Let's take first 3 natural odd numbers. 
First 3 natural odd numbers → 1, 3, 5
Sum of first n natural numbers = $n^{2}$
Sum of first 3 natural numbers = $3^{2}$
1 + 3 + 5 = $3^{2}$
9 = 9
This proves that sum of first n natural numbers is $n^{2}$.
