If a number x is in the interval from 10 to 20 inclusive, increase it by 5, otherwise decrease it by 3. Output the resulting number. Fill in the code.

Here is the completed code to solve the problem:

import random
random.seed(61)
x = random.randint(14, 25)
if 10 <= x <= 20:
    x = x + 5
else:
    x = x - 3
print(x)

Explanation:

1. First, we import the random module and seed the random number generator for consistent results.
2. We generate a random integer x between 14 and 25 (inclusive). Note that the original code specified randint(14, 25), which is fine.
3. We use an if statement with a combined condition 10 <= x <= 20 to check if x falls within the range [10, 20].
4. If the condition is true (i.e., x is between 10 and 20), we increase x by 5: x = x + 5.
5. Otherwise (else), we decrease x by 3: x = x - 3.
6. Finally, we print the updated value of x.
