Question

Which best describes the rule for this pattern? 1,-12,12,-1 A.) subtract 13, then add 24 B.) subtract -13, then add 24 C.) subtract -24, then add 13 D.) subtract 24, then add 13

Answer 1

Answer:

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
