The sum of the first 20 even numbers... is 110
int i, sum = 0; for (i=0; i<20; i+=2) sum+=i;
The sum of the squares of the first 20 natural numbers 1 to 20 is 2,870.
To find the sum of all even numbers between 10 and 20, we first need to identify the even numbers in that range. The even numbers between 10 and 20 are 10, 12, 14, 16, and 18. Adding these numbers together, we get 10 + 12 + 14 + 16 + 18 = 70. Therefore, the sum of all even numbers between 10 and 20 is 70.

The sum of the first 20 even numbers... is 110
var sum = 0; for (var i = 0; i < 20; i++) { sum = sum + i * 2; }
int i, sum = 0; for (i=0; i<20; i+=2) sum+=i;
The sum of the squares of the first 20 natural numbers 1 to 20 is 2,870.
The answer is 20*20 = 400
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.

It is 155 greater.
210
The numbers are 20, 22, 24 and 26.
The numbers are 20, 22, 24 and 26.
