How do you find the sum of consecutive even numbers?
Basically, the formula to find the sum of even numbers is n(n+1), where n is the natural number. We can find this formula using the formula of the sum of natural numbers, such as: S = 1 + 2+3+4+5+6+7…+n. S= n(n+1)/2. To find the sum of consecutive even numbers, we need to multiply the above formula by 2. Hence, S e = n(n+1)
