The sum of the first 200 even numbers is 40,200.
40 and 50
K is a set of five consecutive prime numbers such that the sum of all the elements in K is greater than 200 and less than 300. Which of the following cannot be the sum of the elements in the set K?
200
1,815
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.
200*50=10000
7500
20100
The sum of the first 200 natural numbers is 20,001.
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 value of the greatest integer is 76. This occurs when the set of five consecutive integers is all even numbers.
The sum of 2 to 200 = 10,100
An integer.
