The answer is C: 25.

The rule

Take away 4 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 = 49
for step in range(7):
    print(number)
    number = number - 4

When you run it, Python prints:

49
45
41
37
33
29
25
