Answer 3

To find the sum of the first 1000 natural numbers (1 + 2 + 3 + ... + 998 + 999 + 1000), you can use the formula for the sum of an arithmetic series:

Sum = (n/2) * (first term + last term)

In this case: n = 1000 (the number of terms) first term = 1 last term = 1000

Substitute these values into the formula:

Sum = (1000/2) * (1 + 1000) Sum = 500 * 1001 Sum = 500,500

So, the sum of the first 1000 natural numbers is 500,500.
