Question

Find the sum of the first n odd natural numbers and the first n even natural​

Answer 1

Answer:

To find the sum of first n odd numbers we can apply odd number theorem, it states that the sum of first n odd numbers is equal to the square of n. if we apply odd number theorem: sum of first 10 odd numbers = n * n = 10 * 10 = 100.12

The sum of the first n even natural numbers is n [n + 1].
