Sum of First Ten Even numbers

Number of consecutive even numbers (n)	Sum of even numbers (Sn = n (n+1))	Recheck
5	5(5+1) = 5 x 6 = 30	2+4+6+8+10 = 30
6	6(6+1) = 6 x 7 = 42	2+4+6+8+10+12 = 42
7	7(7+1) = 7×8 = 56	2+4+6+8+10+12+14 = 56

What is the sum of all even numbers from 1 to 200?

We are familiar that, from 1 to 200, there are in total 100 even numbers. Therefore, n =100 Using the formula for sum of even numbers we know; Sn = n (n+1)

How to calculate the sum of even numbers in C++?

In this C++ program to calculate the sum of even Numbers, we altered the for loop (for (number = 2; number <= maximum; number = number + 2)) to remove the If statement. As you can see, we incremented the number to 2 (instead of 1 number++). As we know, every number starts from 2 with an increment of 2 will be an even number.
