Question

Find the sum of 1+2+3+4+5+....................100​

Answer 1

Sum of first 'n' natural numbers is given by:

Sum = n(n+1)/2

So, according to the question: n = 100

Therefore, Sum = n(n+1)/2

= 100(100+1)/2

= 100(101)/2

= 50(101)

= 5050

Hence, sum of the given series is 5050.

Answer 2

Answer:

5050 is your correct answer
