• first element of all row is 1.
  
• last element of all row is same as starting element.
• second last element of all row is same as second element and so on.
• a[2,1]=a[1,0]+a[1,1]; for second row second element.
• a[3,1]=a[2,0]+a[2,1]; for third row second element,a[3,2]=a[2,1]+a[2,2]; for third row third element and so on.

If you want it's program in any language then reply me.
