Answer 2

Question:

Write a program to print the first 15 numbers of the Pell series. Pell series is such a series which starts from 1 and 2 , and subsequent numbers are the sum of twice the previous number and the number previous to the previous number. Pell series: 1, 2, 5, 12, 29, 70, 169, 408, 985, 2378, 5741, 13860, …

Solution:

Language used: Java

public class PellSeries

{

static void main()

{

int i,a=1,b=0,c;

System.out.println("Pell series =");

for(i=1;i<=15;i++)

{

c=a+2*b;

System.out.print(c+" ");

a=b;

b=c;

}

}

}
