Natural Numbers from 1 to 100 |Sum of natural numbers from 1
https://www.cuemath.com/numbers/natural-numbers-from-1-to-100/
Web ResultThe sum of all natural numbers 1 to 100 can be calculated using the formula, S= n/2 [2a + (n − 1) × d], where n is the total number of natural numbers from 1 to 100, d is the difference between the two consecutive terms, and a is the first term. There are a total of 100 natural numbers, so n = 100. Thus, a = 1, d = 1 and n = 100.
