Let P(n) be "a postage of n cents can be formed using 5-cent and 17-cent stamps if n is greater than 63".Basis step: P(64) is true since 64 cents postage can be formed with one 5-cent and one 17-cent stamp.Inductive step: Assume that P(n) is true, that is, postage of n cents can be formed using 5-cent and 17-cent stamps. We will show how to form postage of n + 1 cents. By the inductive hypothesis postage of n cents can be formed using 5-cent and 17-cent stamps. If this included a 17-cent stamp, replace this 17-cent stamp with two 5-cent stamps to obtain n + 1 cents postage. Otherwise, only 5-cent stamps were used and n 65. Hence there are at least three 5-cent stamps forming n cents. Remove three of these 5-cent stamps and replace them with two 17-cent stamps to obtain n + 1 cents postage.Hence P(n + 1) is true.

Answer:
The Proper codes in Line a and Line b is given below
average=Sum/3
print (" Average is = ", average)
Explanation:
In the given question it calculated the sum but the program does not calculate the average of the 3 numbers.The average of the 3 number is calculated by using average=Sum/3 statement so we add this code in Line a then After that print the value of average by using the print function so we add this code in Line b.
Answer:
In Python:
num = int(input("Enter number: "))
maxn = num
while num >=0:
if num>maxn:
maxn = num
num = int(input("Enter number: "))
print("Largest: "+str(maxn))
Explanation:
Get input from the user
num = int(input("Enter number: "))
Initialize the largest to the first input
maxn = num
This loop is repeated until a negative input is recorded
while num >=0:
If the current input is greater than the previous largest
if num>maxn:
Set largest to the current input
maxn = num
Get another input from the user
num = int(input("Enter number: "))
Print the largest
print("Largest: "+str(maxn))
