The answer is B: 20.

The rule

Take away 3 each time.

The pattern as Python code

Here is a tiny Python program that follows the same rule. Type it into IDLE and run it to print the whole pattern, including the answer.

number = 38
for step in range(7):
    print(number)
    number = number - 3

When you run it, Python prints:

38
35
32
29
26
23
20
