Sum of Natural Numbers 1 to 100


The natural numbers from 1 to 100 can be written as 1, 2, 3, 4,5…….100 is an arithmetic progression (A.P). The 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

Let's calculate the sum of the natural numbers 1 to 100

The sum of an A.P,

S = n/2<2a + (n − 1) × d>

S = 100/2<2 + (100 – 1) × 1>

S = 50 <2 + 99>

S = 5050

Therefore, the sum of natural numbers from 1 to 100 is 5050.
