1 Sum of first n natural numbers = n(n+1)2
[Formula.]
2 Arthmetic mean of first n natural numbers = Sum of the numbers n
[Formula.]
3 = n(n+1)2n = n+12
4 So, the Arthmetic mean of first n natural numbers = n+12

Program to calculate the sum of first ten natural numbers?
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.
How many prime numbers are there upto 10 20 30 40 50 and so on what will you notice?
Well, you can look it up yourself in a table of prime numbers. But the general tendency is that, the higher you go, the less prime numbers you'll find in each interval. The long-term tendency is that among the first "n" numbers, you'll find n / ln(n) prime numbers, where ln(n) is the natural logarithm. This formula is not terribly accurate for small numbers, but it gets better and better as "n" gets larger.
Identify the difference between natural number and real number?
The set of natural numbers or counting numbers N is a subset of the set of real numbers R. N = {1, 2, 3, ...) R = {..., -2, -1, -0.5, 0, 1, √2, 2, 3, π, ...}
What is the algorithm and flowchart to find Sum of natural numbers from 1 to10?
The general equation to find the sum of the numbers 1 to n is: (n*(n+1))/2So, for n=10, you have:(10*(10+1))/2(10*11)/2110/255
The sum of two consecutive odd numbers is the square of the product of the first and fourth prime numbers what are the two odd numbers?
Let n = smallest of the odd numbers, then let n+2 = the larger of the two numbers (Remember, 1 is not a prime number.) n+ n+2 = {(2)(7)}2 2n +2 = 142 2n = 196 -2 2n = 194 n = 97 n + 2 = 99
How do you find the mean of first n natural numbers?
The sum of the first n natural numbers is n*(n+1)/2 There are n numbers so their mean = (n+1)/2
What is the program to calculate the average of first 'n' natural numbers?
printf ("%g\n", (n+1.0)/2);
Why they gave a symbol N for natural numbers?
N stands for natural/normal. it was the first set of numbers ever classified, and was actually only classified after imaginary and complex numbers, coz before that, there was no need.
What is the sum of the first 225 natural numbers?
Formula for sum of first natural number = n(n+1)/2 , here n=225 so, answer is 225(225+1)/2 = 25425
What is the sum of the squares of the first 20 natural numbers 1 to 20?
The sum of the first N square numbers is: N*(N+1)*(2N+1)/6 So putting N = 20 gives 2870.
Find the mean of n natural numbers?
Mean = (sum of the n numbers)/n
How do you write a c program to generate first n natural numbers using a for loop?
#include<stdio.h> main(void) { int n; int i; printf("Type n: "); scanf("%d",&n); for(i=1;i<=n;i++) //generates natural numbers from 1,....,n. printf("%d\n",i); //prints these numbers to standard output }
Find the coefficient of variation for first 'n' natural nombers?
I have found the coefficient of variation of the first natural numbers and also other functions.
What is the Sum of first n natural numbers?
int sum = 0; int i; for(i = 0; i < n; ++i) { sum += i; }
What is the sum of two consecutive natural numbers is 525?
Let n be an arbitrary natural number. The next larger natural number is n + 1. The sum of these natural numbers is n + (n + 1) n + (n + 1) = 525 2n + 1 = 525 2n = 524 n = 262 n + 1 = 263. The two natural numbers are 262 and 263.
What is the sum of the numbers from 1 to 100?
Sum of first n natural numbers is (n) x (n + 1)/2 Here we have the sum = 100 x (101)/2 = 50 x 101 = 5050
