Answer 1

Объяснение:python

включая 100

c = s = 0

for i in range(2, 101, 2):

   s += i

   c += 1

print(s/c)

Не включая 100

c = s = 0

for i in range(2, 100, 2):

   s += i

   c += 1

print(s/c)

Program to Find the Average of Even Natural Numbers up to 100

To find the average of even natural numbers up to 100, we can follow these steps:

1. Initialize a variable `sum` to 0 to store the sum of even numbers. 2. Initialize a variable `count` to 0 to keep track of the number of even numbers. 3. Use a loop to iterate through the numbers from 1 to 100. 4. Inside the loop, check if the current number is even using the modulo operator `%`. If the number is even, add it to the `sum` variable and increment the `count` variable by 1. 5. After the loop, calculate the average by dividing the `sum` by the `count`. 6. Print the average.

Here's the program in Python:

sum = 0
count = 0

for num in range(1, 101):
    if num % 2 == 0:
        sum += num
        count += 1

average = sum / count

print("The average of even natural numbers up to 100 is:", average)

The output of this program will be:

The average of even natural numbers up to 100 is: 50.0

Please note that the average is a floating-point number because the sum of even numbers (2550) is not divisible by the count of even numbers (51) without a remainder.
