18 Αυγ 2024 · Sum of first n Odd Numbers is often represented by the formula expressed as n2 where n is a natural number. This formula can be used to calculate the sum of the first n odd numbers without adding them individually.
First 50 odd natural numbers are: 1, 3, 5, 7, ... First term (a) = 1 Common difference (d) = 3 – 1 = 2 Now, S n = n 2 2 a + n-1 d S 50 = 50 2 2 a + 50-1 d = 25 2 1 + 49 2 = 25 2 + 98 = 25 × 100 = 2500 Hence, the sum of first 50 odd natural numbers is 2500.

Answer. \ (2500\) 2500. Explanation. The odd numbers form an arithmetic sequence with \ (a=1\) and \ (d=2\). The \ (n\)th term is \ (a_ {n}=1+2\left (n-1\right)=2n-1\) so, the \ (50\)th odd number is \ (a_ {50}=2\left (50\right)-1=99\). Substituting in Formula \ (2\) for the partial sum of an arithmetic sequence, we get.
