Sum of N Natural Numbers or Positive Integers Formula

Sum of N Natural Numbers or Positive Integers Formula

In previous video lesson we learned to find the sum of an arithmetic progression if we get the first term (a), common difference ( n) and the number of terms ( n).

Now in this video we are going to find ” Sum of N Natural Numbers or Positive Integers Formula”
Actually we will derive a formula for sum natural numbers or positive integers by using the concept of Arithmetic progression.
The formula for sum of natural numbers or positive integers is given by :
Sum of Natural Numbers = n (n+1)/2
Where n = number of terms in the Arithmetic progression of natural numbers.
So how to derive this formula from the concept of sum of arithmetic progression. Lets learn. I hope you are sitting with pen and notebook.

How was it dear?
After learning this videos lesson you are able to find easily the sum of any natural numbers. Lets try this problem.
