The sum of odd numbers from 1 to 9 = 1 + 3 + 5 + 7 + 9 (5 numbers) = 25 = 52 The sum of odd numbers from 1 to 11 = 1 + 3 + 5 + 7 + 9 + 11 (6 numbers) = 36 = 62By the above observation, we can derive a formula that "the sum of first n odd numbers is ...
Sum of n odd numbers: We already know that an odd number has the general form (2n – 1), where n is an integer. In addition, the difference between two successive odd numbers is two. As a result, an arithmetic progression is formed by the odd integers. Here’s how to calculate the...
