The first five prime numbers are 2, 3, 5, 7, 11. The sum of these five numbers is 28.
multiply the mean by the amount of numbers
The answer is the 100th triangular number so you can use the formula (n(n+1))/2.n = 100 so the sum is (100 x 101)/2 = 10100/2 = 5,050.
You use the formulae (n^2 + n)/2 So as n = 200 that would be 20,100
You add the two numbers together, then divide the sum by two.
The sum of the first "n" numbers is equal to n(n+1)/2.
The first five prime numbers are 2, 3, 5, 7, 11. The sum of these five numbers is 28.
If the question is asking for the sum of natural numbers between two members of N, then you will have to add all the natural numbers between the two numbers (excluding the actual two numbers). For example, if they ask you to calculate the sum between 2 and 5, your answer should be 3+4=7.
Can you please provide more details about what you would like to calculate?
To calculate the sum of the numbers 1 to n, the formula is: sum = n(1 + n) / 2 So, an equation to find the sum of the integers 1 to 2010 is: sum = 2010 x (1 + 2010) / 2
Mean is the average number in a set of data. To calculate mean, you add up all the numbers in a set of data and divide that sum by the amount of numbers you just added up. Example: numbers: 2, 2, 1, 3 2+2+1+3=8 How many numbers in the set? There are 4 so you divide the sum we just found by 4. 8 divided by 4=2 The mean/average of this set of data is 2.

If the sum of 2 numbers is 25 and their product is 156, the 2 numbers would be 12 and 13.
Algorithm to find the sum of first n natural numbers:1. Read n.2. Initialize N=1.3. Initialize sum S=0.4. Calculate S=S+N.5. Calculate N=N+1.6. If N>n, then goto step 7 else goto step 4.7. Write the sum S.8. Stop.
If the sum of 2 numbers is 25 and their product is 156, the numbers are 12 and 13.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
