Question 3 • EF Math 12 1st Nine Weeks

Identify the pattern for the following sequence. Find the next three terms in the sequence.-15, -11, -7, -3, ____, ____, ____,...

Answer
A
Subtract 4; -7, -11, -15
B
Add 4; 2, 6, 10
C
Subtract 4; 1, 5, 9
D
Add 4; 1, 5, 9

Explanation

Each term increases by 4: −15 to −11, −11 to −7, and −7 to −3. Continuing the pattern gives −3 + 4 = 1, then 1 + 4 = 5, and 5 + 4 = 9. So the pattern is “Add 4,” and the next three terms are 1, 5, and 9.
