The reasoning is like this
2 + 13*1 = 15
15 + (13 * 2) = 41
41 + (13 * 3) = 80
80 + (13 * 4) = 132
132 + (13 * 5) = 197.

so logic should be
res=(seed+(13*i))
seed=res;
cw(res)
public void yourMethod()
{
int n= Convert.ToInt32(txtLenghth.Text); // a textbox in winform
int seed=2;
int res=0;
List<int> series= new List<int>(){seed};
for(int i=0;i
{
res=(seed+(13*i))
seed=res;
series.Add(res);

}
var commaSeparated=string.Join<int>(", ", series);
txtSeries.Text=commaSeparated; // another textbox to display

1. using System;
3. class Program
4. {
5. static void Main() {
6. int a = 2, total = 9;
8. for (int i = 1; i <= total; i++) {
9. Console.Write(a + " ");
10. a += 13 * i;
11. }
12. }
13. }
18. /*
19. run:
21. 2 15 41 80 132 197 275 366 470
23. */

You can also write your custom code in you windows form like:

public static string getSeries(int startVal, int diff, int NthVal)
{
string series = "[" + startVal;
int prevVal = startVal;
for (int i = 0; i < NthVal; i++)
{
if (i > 0)
{
prevVal = prevVal + (diff * i);
series += ", " + prevVal;
}
}
series += "]";
return series;
}

Call your method in your class as:

string series = getSeries(2, 13, 6);

Found it on internet, you can implement it using winform as you wish

using System;

class GFG{

static void printSeries(int N)

{

int ith_term = 0;

// Generate the ith term and

for(int i = 1; i <= N; i++)

{

ith_term = (13 * i * (i - 1)) / 2 + 2;

Console.Write(ith_term + ", ");

}

}

// Driver Code

public static void Main(String[] args)

{

int N = 7;

printSeries(N);

}

}
