How do you find the sum of odd numbers?
The sum of odd numbers can be calculated using the formula Sn= 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 Sn= n2. To calculate the sum of odd numbers between 1 to 20 we will use Sn= n2 where n = 10 as there are 10 odd numbers between 1 to 20.
