start_number = 20

end_number = 40

sum_of_numbers = 0

for num in range(start_number, end_number + 1):

   sum_of_numbers += num

print("Сума чисел від {} до {}: {}".format(start_number, end_number, sum_of_numbers))

2

n = int(input("Введіть значення n: "))

product = 1

for i in range(1, n + 1, 2):

   fraction = 1 / i

   product *= fraction

print("Добуток дробів 1/1, 1/3, 1/5, ..., 1/{}>>> {}".format(n, product))

Sum of Numbers from 20 to 40

To find the sum of numbers from 20 to 40, you can use the formula for the sum of an arithmetic series. The formula is:

Sum = (n/2)(first term + last term)

In this case, the first term is 20 and the last term is 40. We need to find the value of n, which represents the number of terms in the series.

To find the number of terms, we can subtract the first term from the last term and add 1:

n = last term - first term + 1

Substituting the values, we get:

n = 40 - 20 + 1 = 21

Now we can calculate the sum using the formula:

Sum = (21/2)(20 + 40) = 21 * 60 = 1260

Therefore, the sum of numbers from 20 to 40 is 1260.

Product of Fractions from 1/1 to 1/n

To find the product of fractions from 1/1 to 1/n, we need to multiply all the fractions together. The given fractions form a harmonic series, where the denominator increases by 2 each time.

Let's calculate the product step by step:

1. Start with the first fraction: 1/1. 2. Multiply it by the next fraction: 1/3. 3. Multiply the result by the next fraction: 1/5. 4. Continue this process until we reach the fraction 1/n.

The product of fractions can be represented as:

Product = (1/1) * (1/3) * (1/5) * ... * (1/n)

To simplify the calculation, we can rewrite the product as:

Product = 1 / (1 * 3 * 5 * ... * n)

Now, let's calculate the product using this formula.

Please provide the value of n, and I will calculate the product for you.
