Answer 2

Answer:

The sum of the first $150$ positive integers is $11,325$

Step-by-step explanation:

Given:

To find the sum of the first $150$ positive integers.

The series will be as $1,2,3,4,...150$

It is same like sum of first n natural numbers.

we know as

$\frac{n(n+1)}{2}$

So here $n=150$ then we get as

$=\frac{150*151}{2} \\\\=75*151\\\\= 11,325$
