Python

n = 5

p = 1
b = total - n * 2 + 4

for x in range(1, n + 1):
  for y in range(1, x + 1):
    if y == 1:
       print("{:2d}".format(p), end="")
       p += 1
    elif x == n:
       print("{:2d}".format(b), end="")
       b += 1
    elif y == x:
       print("{:2d}".format(h), end="")
       h -= 1
    else:
       print("  ", end="")  # 2ws
  print()
