    Default Question on math's loop sequence

    (b) 1 3 6 10 15 21
    I want my loop to have this output.
    Is there an easier way than my current code?
    for(int i=1;i<=6;i++)
    {
    int d=i*(i+1)/2;
    System.out.print(d+ " ");
    }

    What do you mean by easier?
    One shortening of the code would be to remove the d variable and print the value of the expression.
    If you don't understand my answer, don't ignore it, ask a question.

    here a different way to get the same results( looks more easy to understand)
    [code]
    int i =1, total = 1;
    for(int x = 1; x<6; x++){
    i++
    total = total + i;
    System.out.println(total);
    }

    [code]

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
