What numbers should replace the question marks in the sequence?
Correct answer: 26, 25
Explanation:
The sequence is 116, 80, 55, 39, 30, ?, ?.
Look at the differences between the numbers:
116 - 80 = 36
80 - 55 = 25
55 - 39 = 16
39 - 30 = 9
The sequence is subtracting square numbers:
36 = 6²
25 = 5²
16 = 4²
9 = 3²
So the next square numbers to subtract are:
2² = 4
1² = 1
Continue the sequence:
30 - 4 = 26
26 - 1 = 25
Therefore, the missing numbers are 26 and 25.
