int i;
for (i = 100; i <= 200; i++)

Answer 1

private void button1_Click(object sender, EventArgs e)
{
    List<int> numbers = new List<int>();
    for (int i = 100; i <= 200; i++)
    {
        if (i % 3 != 0)
        {
            numbers.Add(i);
        }
    }

    for (int i = 0; i < numbers.Count; i++)
    {
        richTextBox1.AppendText(numbers[i].ToString());

        if ((i + 1) % 5 != 0)
        {
            if (i != numbers.Count - 1)
            {
                richTextBox1.AppendText("\t");
            }
        }
        else
        {
            richTextBox1.AppendText(Environment.NewLine);
        }
    }
}
