C

#include<stdio.h>

int main()
{
  int n=5; //size
  int z=1;
  int i,j,k;

  for(i=1; i<=n; i++)
  {
    for(j=n-1; j>=i; j--)
    {
      printf(" ");
    }
    for(k=1; k<=z; k++)
    {
      printf("%d",k);
    }
    z+=2;
    printf("\n");
  }
  return 0;
}

C++

 #include<iostream.h>
 
 int main()
 {
 int z=1;
 
 for(int i=0;i<5;i++){
 for(int j=4;j>i;j--)
 {
 cout<<" ";
 }
 for(int k=1;k<=z;k++)
 {
 cout<<k;
 }
 z+=2;
 cout<<endl;
 }
 return 0;
 }

Java

   class PatternProg
   {
     public static void main(String args[])
     {
 int n=5; //size
 int z=1;
 
 for(int i=0;i<n;i++){
 for(int j=n-1;j>i;j--)
 {
 System.out.print(" ");
 }
 for(int k=1;k<=z;k++)
 {
 System.out.print(k);
 }
 z+=2;
 System.out.println();
 }
     } //end of main
 }  //end of class

C#

using System;

class PatternProg
{
  public static void Main()
  {
    int n = 5; //size
    int z = 1;

    for (int i = 0; i < n; i++)
    {
      for (int j = n - 1; j > i; j--)
      {
        Console.Write(" ");
      }
      for (int k = 1; k <= z; k++)
      {
        Console.Write(k);
      }
      z += 2;
      Console.WriteLine();
    }
    Console.ReadKey(true);
  } //end of main
} //end of class

Python

inc = 1
for x in range(5, 0, -1):
    for y in range(x, 0, -1):
        print(" ", end="")
    for z in range(1, inc + 1):
        print(z, end="")
    inc += 2;
    print()
