    How do I figure out what 10 plus 10 is, recurring ( say fifty times)?

    10 + 10 = 20
    10 x 2 = 20

    10 + 10 + 10 = 30
    10 x 3 = 30

    10 x 50 =....

    Thanks partyjungle.
    But I actually asked it completely wrong. Sorry about that.
    I meant;
    initial value 10

    plus 10 = 20
    plus 20 = 40
    plus 30 = 70
    etc.

    Do you know any programming?

    I wrote a small snippet of java to do this.

    [HTML]public class MyClass {
    public static void main(String args[]) {
    int x = 10;
    for (int i = 1; i < 51; i++){
    x = x + (i * 10);
    System.out.println("Sum of x = " + x);
    }

    System.out.println("Total sum of x = " + x);
    }
    }[/HTML]

    Input it here to see it run: https://www.jdoodle.com/online-java-compiler
