# Java Program to Print Series 1,2,9,28,65

### How to print this series?

Below is the logic to solve the series,

1 = (0 * 0 * 0) + 1
2 = (1 * 1 * 1) + 1
9 = (2 * 2 * 2) + 1
28 = (3 * 3 * 3) + 1
65 = (4 * 4 * 4) + 1

We are going to see two solutions here to print this series,

### Solution #1:

```package com.javacodepoint.series;

import java.util.Scanner;

/**
* Series pattern: 1, 2, 9, 28, 65
*
* @author javacodepoint.com
*
*/
public class SeriesPattern1 {

public static void main(String[] args) {

// Create scanner object to read user inputs
Scanner sc = new Scanner(System.in);

System.out.println("Enter no. of elements you want in the series: ");
int n = sc.nextInt();

System.out.print("Series: ");
for (int i = 0; i < n; i++) {

// Calculate the element of the series
int element = (i * i * i) + 1;

// Print the element with comma(,) separator
System.out.print(element + ", ");
}
}
}

```

OUTPUT:

Enter no. of elements you want in the series:
7
Series: 1, 2, 9, 28, 65, 126, 217,

### Solution #2:

By using Math.pow() method,

```package com.javacodepoint.series;

import java.util.Scanner;

/**
* Series pattern: 1, 2, 9, 28, 65
*
* @author javacodepoint.com
*
*/
public class SeriesPattern2 {

public static void main(String[] args) {

// Create scanner object to read user inputs
Scanner sc = new Scanner(System.in);

System.out.println("Enter no. of elements you want in the series: ");
int n = sc.nextInt();

System.out.print("Series: ");
for (int i = 0; i < n; i++) {

// Calculate the element of the series
int element = (int) (Math.pow(i, 3) + 1);

// Print the element with comma(,) separator
System.out.print(element + ", ");
}
}
}

```

OUTPUT:

Enter no. of elements you want in the series:
6
Series: 1, 2, 9, 28, 65, 126,
