Identify the pattern for the following sequence. Find the next three terms in the sequence.5, 2, -1, -4, ____, ____, ____,...
a.
Subtract 3; -7, -10, -13
b.
Add 3; -7, -10, -13
c.
Subtract -3; 7, 10, 13
d.
Add 3; 1, 4, 7

Answers

In this pattern, we're subtracting 3, so after -4, we'd get -7, -10 and -13, which would be option A

Final answer:

The pattern in this sequence is subtracting 3 each time. The next three terms in the sequence are -7, -10, and -13, making the correct answer option a.

Explanation:

The pattern in this sequence is decreasing by 3 each time. To find the next number in the sequence, we subtract 3 from the last number. So, for this numerical sequence: 5, 2, -1, -4, the next three terms would be -7, -10, and -13. Therefore, the correct answer is option a which states: Subtract 3; -7, -10, -13.

Let's explain this in steps:

We begin with 5.
Subtract 3 from 5, we get 2.
Subtract 3 from 2, we get -1.
Subtract 3 from -1, we get -4.
Continuing this pattern, subtract 3 from -4, we get -7 (first next term).
Subtract 3 from -7, we get -10 (second next term).
Subtract 3 from -10, we get -13 (third next term).
