The sum of the first 200 natural numbers is 20,001.
The sum of all the numbers 1 through 200 is 20,100.
The sum is infinite
200*50=10000
This is the way I would do it: The sum of the 1st & 100th numbers = the sum of the 2nd & 99th numbers = the sum of the 3rd & 98th numbers all the way to the sum of the 50th & 51st numbers; each of the sums equals 200. So I would multiply 200 by 50 (10000).
The sum of the first 200 natural numbers is 20,001.
The sum of all the numbers from 101 through 200 is 15,050.
The sum of all the numbers 1 through 200 is 20,100.
The sum of the first 200 even numbers is 40,200.
The sum is infinite
200*50=10000
7500
This is the way I would do it: The sum of the 1st & 100th numbers = the sum of the 2nd & 99th numbers = the sum of the 3rd & 98th numbers all the way to the sum of the 50th & 51st numbers; each of the sums equals 200. So I would multiply 200 by 50 (10000).
200*201/2=20100
Look up Gauss' Formula if you want to know how to calculate this. If you just want the answer, it's 20100.
The sum of the first 50 natural numbers is 1,251.
The sum of 2 to 200 = 10,100
