Number Sequence

03Nov13

In the twelve months from March 2013 to March 2014, I programmed solutions to the problems posted on the Contest Coding blog run by Lewis Cornwall, solving 33 problems (out of 47) and achieving a position of 4th on the leaderboard (out of 23).

As that blog has now been discontinued, I’m posting here the solutions I programmed to those problems.

Number Sequence

A number sequence begins as follows:

6, 10, 14, 18, 22

If 6 is the first term, and 10 the second, find the one billionth term.

Solution and answer (Number_Sequence.java):

public class Number_Sequence
{
  public static void main( String p[] )
  {
    System.out.println( new Date());

    long term = 1000000000;
    term = term * 4 + 2;
    System.out.println( "\n" + term + "\n" );

    System.out.println( new Date());
  }
