What numbers should replace the question marks in the sequence?
Correct answer: 42, 45
Explanation:
The sequence is 20, 12, 39, 35, 44, ?, ?.
Look at how the numbers change:
20 - 8 = 12
12 + 27 = 39
39 - 4 = 35
35 + 9 = 44
The pattern alternates between subtracting powers of 2 and adding powers of 3:
-8 = -2³
+27 = +3³
-4 = -2²
+9 = +3²
So the next steps are:
-2 = -2¹
+3 = +3¹
Continue the sequence:
44 - 2 = 42
42 + 3 = 45
Therefore, the missing numbers are 42 and 45.
