Reading the number series without using a loop

def ShowNumber(N, Original, K, flag):
#To print the number
print(N, end = " ")
# change flag if the number becomes negative

if (N <= 0): 
    if(flag==0): 
        flag = 1
    else: 
        flag = 0
      
# base condition for second_case (Adding K) 
  
if (N == Original and (not(flag))): 
    return
  
# if flag == true, we subtract value until the number is greater then zero 
if (flag == True): 
    ShowNumber(N - K, Original, K, flag) 
    return
# second case (Addition ) 
if (not(flag)): 
    ShowNumber(N + K, Original, K, flag); 
    return

N = 20
K = 6
ShowNumber(N, N, K, True)
