查找系列3、14、39、84的第n项…

给定一个数字N。任务是编写一个程序,在下面的系列中查找第N项:

null

3, 14, 39, 84…

例如:

Input: 3Output: 39For N = 3Nth term = ( 3*3*3 ) + ( 3*3 ) + 3         = 39Input: 4Output: 84

计算级数第n项的公式:

Nth term = ( N*N*N ) + ( N*N ) + N 

以下是所需的实施:

C++

// CPP program to find N-th term of the series:
// 3, 14, 38, 84...
#include <iostream>
using namespace std;
// calculate Nth term of series
int nthTerm( int N)
{
return (N * N * N) + (N * N) + N;
}
// Driver Function
int main()
{
int N = 3;
cout << nthTerm(N);
return 0;
}


JAVA

// Java program to find Nth number
import java.io.*;
// calculate Nth term of this series
class GFG
{
public int nthTerm( int N)
{
// By using above formula
return (N * N * N) + (N * N) + N;
}
// Driver Code
public static void main(String[] args)
{
int N = 3 ;
GFG a = new GFG();
// call and print Nth term
System.out.println(a.nthTerm(N));
}
}


Python 3

# Python 3 program to find  N-th
# term of the series:
# 3, 14, 38, 84...
# Function to calculate Nth term of series
def nthTerm(n) :
return (N * N * N) + (N * N) + N
# Driver code
if __name__ = = "__main__" :
N = 3
# function calling
print (nthTerm(N))

C#

// C# program to find Nth number
using System;
// calculate Nth term of this series
class GFG
{
public int nthTerm( int N)
{
// By using above formula
return (N * N * N) + (N * N) + N;
}
// Driver Code
public static void Main()
{
int N = 3;
GFG a = new GFG();
// call and print Nth term
Console.WriteLine(a.nthTerm(N));
}
}

PHP

<?php
// PHP program to find N-th term
// of the series: 3, 14, 38, 84...
// calculate Nth term of series
function nthTerm( $N )
{
return ( $N * $N * $N ) +
( $N * $N ) + $N ;
}
// Driver Code
$N = 3;
echo nthTerm( $N );

Javascript

<script>
// JavaScriptprogram to find N-th term of the series:
// 3, 14, 38, 84...
// calculate Nth term of series
function nthTerm( N)
{
return (N * N * N) + (N * N) + N;
}
// Driver Function
let N = 3;
document.write(nthTerm(N));
// This code contributed by Rajput-Ji
</script>


输出:

39
