Answer:
The sum of all natural numbers from 1 to 100 is 5050.
Step-by-step explanation:
Let S be the required sum.
Clearly, it is an Arithmetic Progression whose first term (a) = 1, last term (l) = 100 and number of terms (n) = 100.
We know the formula for finding sum,
Sn=n/2[2a+(n-1)d]
Sn=100/2[2(1)+99(1)]
Sn=50*101=5050
Therefore, the sum of first 100 natural numbers is 5050.
Hope it helps you..
