What numbers should replace the question marks in the sequence?
Correct answer: 5, 14
Explanation:
The sequence is 27, 9, 18, 6, 15, ?, ?.
The pattern uses two alternating steps:
divide by 3, then add 9.
Follow the pattern:
27 ÷ 3 = 9
9 + 9 = 18
18 ÷ 3 = 6
6 + 9 = 15
So the next steps are:
15 ÷ 3 = 5
5 + 9 = 14
Therefore, the missing numbers are 5 and 14.
