### What is the sum of the first 100 odd natural numbers?

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.

### What is the sum of the first 50 multiples of 6?

Why, that's just 6 times the sum of the numbers from 1 to 50
!
The sum of the numbers from 1 to 50 is:
1 + 50 = 51
2 + 49 = 51
3 + 48 = 51
4 + 47 = 51
5 + 46 = 51
.
.
.
etc. There are 25 pairs, and each pair sums to 51. So the sum of 1
... 50 is (25 x 51) = 1,275.
The sum of the first 50 multiples of 6 is (1,275 x 6) = 7,650.
