The answer is A: 103.

The rule
Add 14 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 = 19
for step in range(7):
print(number)
number = number + 14
When you run it, Python prints:
19 33 47 61 75 89 103
Pixel says: Try changing a number in the code and run it again. Can you make the pattern go on for 20 steps? Meow!
