Yes This pattern Can be print as you want . Here is code stuff to get required OutPut.

You can print for any Number By this logic

C# Code :(For value=6 -you can get pattern for any number according to limit value By changing the value of limit variable)

class Program
{
static int lastprint;
static void Main(string[] args)
{
int count = 0;
int limit = 6;

for (int i = 1; i <= limit; i++)
{
for (int j = 1; j <= i; j++)
{
if (j == 1)
{
Console.Write(i + "\t");
count = 1;
lastprint = i;
}
else
{
int a1 = limit - count;
count = count + 1;
int newnum = lastprint + a1;
lastprint = newnum;
Console.Write(newnum + "\t");
}
}
Console.WriteLine("");
lastprint = 0;
}
Console.ReadLine();
}
}

Output window:

Yes you are right there is a series in each row. .. I didn't notice that 'series'.

I noticed that the differences between the numbers on each line formed a decreasing sequence (i.e. 4, 3, 2, 1) and so I coded it on that basis :)

Thanks Vulpes for your answer... I thought this kind of pattern is not possible in a normal way.

Try:

using System;

class Program
{
static void Main()
{
for(int i = 1; i <= 5; i++)
{
Console.Write("{0} ", i);

int n = i - 1;
int c = 0;
int s = i;

for(int d = 4; d >= 1; d--)
{
if (c == n) break;
s += d;
Console.Write("{0} ", s);
c++;
}

Console.WriteLine();
}

Console.ReadKey();
}
}

I think, without using graphics you can't create above pattern. Since any Console Print method prints characters horizontally (i.e. row by row),
so numbers in each row should follow any kind of mathematical/ logical series (e.g. Arithmetic Progression, GP, HP, etc..).
For example, we could create pattern (as below), where numbers in each row follow some kind of series.
But the pattern you mentioned in the problem, the numbers follow a series in vertical fashion instead of horizontal.

2 3
4 5 6
7 8 9 10
11 12 13 14 15
The code for the above pattern is:
        static void Main()
        {
            int k = 0;
            for (int j = 1; j <= 5; j++)
            {
                for (int i = 1; i <=j; i++)
                {
                    k++;
                    Console.Write(k.ToString()+ " ");
                }
                Console.WriteLine();
            }
            //Just for the hold screen to see output
            Console.Read();
        }
