Question

What is the sum of all even numbers between 100 and 200

Answer 1

We're including the greater part of the even numbers from 100 to 200. There are 100 numbers from 101 to 200, which implies there are 50 even numbers.

Since 100 are additionally incorporated into our total, we're including 51 even numbers all together.

How about we reorder the numbers: 100+102+104+… +198+200 =(100+200)+(102+198)+(104+196)+… +(148+152)+150 If we take a gander at the reordered aggregate, we can see that there are 25 sets of even numbers in addition to an additional 150.

Each combine aggregates to 300, so the aggregate is =25x300+150 =7500+150 =7650.
