Question

Write a program in c++ that finds the sum of the below given sequences, computes the total number of elements given some parameters and also computes the x th term of the series. The x th term is an user input. Also indicate if the below sequences are in arithmetic progression, geometric progression or neither of them.

. Consider a sequence: 1/1! + 2/2! + 3/3! +. . . 1/N!. Find the recurrance relation for the above series, this need not be programmed. Then, compute the sum of ’n’ elements in this sequence where ’n’ is an user input.

Explanation / Answer

#include <stdio.h>

double sumseries(double);

main()

{

    double number,sum;

    cout<<" Enter the value: ";

    cin>>number;

    sum = sumseries(number);

cout<<” Sum of the above series "+ sum);

}

double sumseries(double m)

{

    double sum2 = 0, f = 1, i;

    for (i = 1; i <= m; i++)

    {

        f = f * i;

        sum2 = sum2 +(i / f);

    }

    return(sum2);

}
