Question

find the sum of the all natural no of from 1to1000​

Answer 1

Answer:

500500

Step-by-step explanation:

The sequence of integers starting from 1 to 1000 is given by

1,2,3,4,...,1000

The above sequence has 1000 terms. The first term is 1 and the last term is 1000 and the common difference is equal to 1.

We have the formula that gives the sum of the first n terms of an arithmetic sequence knowing the first and last term of the sequence and the number of terms (see formula above).

s 1000 =[1000(1+1000)]/2​

=500500
