What is the sum of all even numbers from 1 to 10?

Therefore, the first 10 even natural numbers will be 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20. Hence, the required sum of the first 10 even natural numbers is 110.

How do you find the sum of all even numbers between 1 to n using recursion in C?

To find sum of even numbers we need to iterate through even numbers from 1 to n. Initialize a loop from 2 to N and increment 2 on each iteration. The loop structure should look like for(i=2; i<=N; i+=2) . Inside the loop body add previous value of sum with i i.e. sum = sum + i .

How do you find the sum of all even numbers from 1 to 50?

By the definition of even numbers, there even numbers from 1 to 50 include 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50). Thus, n = 25. Substitute the values in the formula Sn = n(n+1).

How do you find the sum of all even numbers from 1 to 100?

The average of even numbers 1 to 100 is 51. This is calculated by using the formula of average, which states that Average = Sum of all values/Total number of values. Here, the sum of values is 2550 and the total number of even numbers from 1 to 100 is 50. So, average = 2550/50 = 51.
