What numbers should replace the question marks in the sequence?
Correct answer: 181, 184
Explanation:
The sequence is 730, 1, 244, 163, 190, ?, ?.
Look at how the numbers change:
730 - 729 = 1
1 + 243 = 244
244 - 81 = 163
163 + 27 = 190
The pattern is alternating subtracting and adding powers of 3:
-729 = -3⁶
+243 = +3⁵
-81 = -3⁴
+27 = +3³
So the next steps are:
-9 = -3²
+3 = +3¹
Continue the sequence:
190 - 9 = 181
181 + 3 = 184
Therefore, the missing numbers are 181 and 184.
