The sum of odd numbers can be calculated using the formula S n = n/2 × [a + l] where 'a' is the first odd number, 'l' is the last odd number and 'n' is the number of odd numbers or S n = n 2. To calculate the sum of odd numbers between 1 to 20 we will use S n = n 2 where n = 10 as there are 10 odd numbers between 1 to 20.

Question 1: What is the sum of odd numbers from 1 to 50? Solution: We know that, from 1 to 50, there are 25 odd numbers. Thus, n = 25. By the formula of sum of odd numbers we know; S n = n 2. S n = 25 2 = 625. Question 2: What is the sum of odd numbers from 1 to 99? Solution: We know that, from 1 to 99, there are 50 odd numbers. Thus, n = 50 ...
22 Οκτ 2024 · The sum of first 50 odd numbers i.e. (1, 3, 5, …., 99) Here, first number (a) = 1 And, Last number (l) = 99 So, Sum = (n/2) × (a + l) = 50/2 &tim.
We know that the total Number of Odd Natural Numbers from 1 to 100 is 50. The other 50 are Even Numbers. Sum of Odd Natural Numbers is given by. S n = n 2 . Hence, we give a sum of the first 50 Odd Natural Numbers by: S 50 = (50) 2. S 50 = 2500. Case 2:
