The Program in C++ to Find out Sum of an A.P. series is given below:
#include <iostream>
using namespace std;
int main() {
int a, d, n;
cout <<"Hello Codeauri Family, enter the first term of the series here:\n";
cin >> a;
cout<< "similarly,enter the common difference here:\n";
cin >>d;
cout<< "and enter the number of terms here:\n";
cin >> n;
int sum = (n * (2 * a + (n - 1) * d)) / 2;
cout << "Well, The sum of the A.P. series is: " << sum << endl;
return 0;
}
Output:
Hello Codeauri Family, enter the first term of the series here:
6
similarly,enter the common difference here:
7
and enter the number of terms here:
5
Well, The sum of the A.P. series is: 100
Pro-Tips💡
This program prompts the user to enter the first term (a), common difference (d) and number of terms (n) of an A.P (Arithmetic progression) series,
then use the formula Sum = n/2 * (2a + (n-1)d) to calculate the sum of the series, and finally print out the result.
It uses standard input/output library
It’s important to note that an Arithmetic Progression is a sequence of numbers in which the difference between any two consecutive terms is always a constant.
