n = int(input('Please enter n: '))#take input n

print('please enter the numbers')#print enter the numbers

total = 0 #intially take total as 0

original_total = 1 #intially take original_total=1

for i in range(2, n+1): #take the range 2 to n+1

total += int(input('Please enter a number: ')) # add total and enter the number

original_total += i

missing = original_total - total #you got missing number original_total - total
