Answer:</h2>
In this exercise we have the following pattern:
1, -12, 12, -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
So the absolute value of -5 is 5
