Answer 2

Given:

The numbers are from 1 to 300.

To Find:

Sum of even numbers between 1 to 300

Solution:

As we know, the even numbers between 1 to 300 are 2,4,6,8......298.

 therefore sum will be,

⇒ 2 + 4 + 6 + ......... + 298

Take 2 common,

⇒ 2 ( 1 + 2 + 3 + 4 +....... 149 )

Sum of natural number is given by = n(n +1 ) / 2

⇒  2 ( 149 × 150 / 2 )

⇒  149 × 150

⇒ 22350

Hence the sum of even numbers between 1 to 300 is 22350.
