给定整数N ,任务是找到以下系列的N项:

例子:

方法:

  • 给定系列0、8、64、216、512、1000、1728,…也可以写成0 *(0 2 ),2 *(2 2 ),4 *(4 2 ),6 *(6 2 ), 8 *(8 2 ),10 *(10 2 ),…
  • 观察到0,2,4,6,10,…是在AP和该序列的第n项可使用下式术语中找到= 1 +(N – 1)* d,其中a 1第一项位置项d共同的区别
  • 要获得原始系列中的术语term =术语*(term 2 ),term 3
  • 最后打印该术语

下面是上述方法的实现:

C++
// C++ implementation of the approach
#include 
using namespace std;
 
// Function to return the nth term of the given series
long term(int n)
{
    // Common difference
    int d = 2;
 
    // First term
    int a1 = 0;
 
    // nth term
    int An = a1 + (n - 1) * d;
 
    // nth term of the given series
    An = pow(An, 3);
    return An;
}
 
// Driver code
int main()
{
    int n = 5;
 
    cout << term(n);
 
    return 0;
}


Java
// Java implementation of the approach
import java.util.*;
import java.lang.*;
import java.io.*;
 
public class GFG {
 
    // Function to return the nth term of the given series
    static int nthTerm(int n)
    {
 
        // Common difference and first term
        int d = 2, a1 = 0;
 
        // nth term
        int An = a1 + (n - 1) * d;
 
        // nth term of the given series
        return (int)Math.pow(An, 3);
    }
 
    // Driver code
    public static void main(String[] args)
    {
        int n = 5;
        System.out.println(nthTerm(n));
    }
}


Python3
# Python3 implementation of the approach
 
# Function to return the nth term of the given series
def term(n):
     
    # Common difference
    d = 2
     
    # First term
    a1 = 0
     
    # nth term
    An = a1 +(n-1)*d
     
    # nth term of the given series
    An = An**3
    return An;
 
     
# Driver code
n = 5
print(term(n))


C#
// C# implementation of the approach
using System;
public class GFG {
 
    // Function to return the nth term of the given series
    static int nthTerm(int n)
    {
 
        // Common difference and first term
        int d = 2, a1 = 0;
 
        // nth term
        int An = a1 + (n - 1) * d;
 
        // nth term of the given series
        return (int)Math.Pow(An, 3);
    }
 
    // Driver code
    public static void Main()
    {
        int n = 5;
        Console. WriteLine(nthTerm(n));
    }
}
