That is simple! Knowing that there are only 8 numbers BETWEEN 1 and 10, half of them even and half odd, you would have the solution:
x+(x+2)+(x+4)+(x+6)=?;x=2 <--- See here i have 4 quantities since half of 8 is 4.
Then if we remove the parentheses, we would have:
=x+x+2+x+4+x+6
Then combine similar terms:
=4x+12
Then substitue the value of x:
=4(2)+12
=8+12
=20

There are 12 even numbers between 2 and 24 inclusive.The sum is 154.
The answer is zero !
The answer to what is the sum of the first positive even numbers is 930. It doesn't mean that you add all the even numbers up until you reach the number 30. In fact, since you have to get the sum of the even numbers, you have to add all even numbers until you get to the number 60.
The sum of all even numbers between 0 and 398 (2-396) is 157,212. If you include 398 the sum is 158,802.

If this question means "in the interval 0 to 16 inclusive, is the sum of the odd numbers the same as the sum of the even numbers ?" then the answer is no. The sum of the even numbers is eight more than the sum of the odd ones.
The answer is zero !
The sum of the first 200 even numbers is 40,200.
well, let's break it down. First, the even numbers between 1 and 11 are, 2,4,6,8,10. Now 2+4=6, 6+6=12, 8+12=20, 20+10=30. So, to answer your question simply, the sum of even numbers between 1 and 11, is 30.

The sum of all prime numbers between 60 and 75 is 272
