Question

find the sum of the first 1000 positive integers and the first N positive integers

plzzz guys solve this​

Answer 1

Answer:

sum of +ve 1000 integers = 5,00,500

Step-by-step explanation:

we have the formula to the sum of first n numbers which is n(n+1)/2

0 is neither +ve nor -ve

so sum of first n +ve integers is n(n+1)/2

and sum of first 1000  +ve integers is n(n+1)/2

=> 1000(1000+1)/2

=> 1000(1001)/2

=> 500(1001)

=> 5,00,500
