In this exercise we have the following pattern:

1, - 12, 12, - 1

So we need to find the rule for this patter. First of all, let's take the first number, which is 1:

1

To find the second number, which is - 12, we must subtract 13, because:

1 - 13 = - 12

To find the third number, which is 12, we must add 24, because:

-12 + 24 = 12

In conclusion, the correct answer is A.) subtract 13, then add 24
