The first 100 odd natural numbers are the number 1-201, ignoring all even numbers.
If you think about this for a moment, you realize that :
1+201 = 202
3+199 = 202
5+197 = 202
etc.
With this, you can pair up all of your numbers leaving you with 50 pairs, all equaling 202.
Ergo: 50*202 = 10100 is your sum.
This is very easy. Simply square the number: 100 squared (100 x 100) = 10,000. So, the sum of the first 100 odd numbers is 10,000.
Their sum is 10000.

the answer is 2500 I am sorry but this answer is wrong. You only added the numbers between 1 and 100. The question is the first 100 odd numbers, you need to add 1 to 197. The correct answer is 10,000.
It is 100^2=10000
The sum is 10,000.
5.
This has no answer. Any five odd numbers will always add to an odd number. 100 is even.
