Find the Sum of all Natural Numbers From 1 to 100

Answer:

Now note the natural numbers, which are from 1-to 100.

According to arithmetic progression, natural numbers can be written down as 1, 2, 3, 4, 5, 6, 7, and 8 to 100. 

• A=1
• D=1
• N=100

Now moving toward the calculation, the sum of all the natural numbers is:

The formula of Arithmetic Progression to calculate:

S= n/2 [2a + (n – 1) * d]

S= 100/2 [2 + (100 – 1) *1]

S= 50 [2 + 99]

S is equal to 5050 

Basically, the sum of the first 100 natural numbers is equal to 5050.
