To solve this sequence, let's analyze the given numbers:
2, 4, 9, 28, 125, 726, ?
Looking at the sequence, we can see that each number is obtained by performing different mathematical operations on the previous number.
To find the pattern, let's examine the differences between consecutive numbers:
4 - 2 = 2
9 - 4 = 5
28 - 9 = 19
125 - 28 = 97
726 - 125 = 601
From these differences, we can see that they are not following a simple arithmetic or geometric progression.
However, if we look closely, we can observe that the differences are increasing significantly with each step.
To continue the pattern, we need to add the next difference to the last number in the sequence:
726 + 601 = 1327
Therefore, the missing number in the sequence is 1327.
None of the options provided match 1327.
Hence, the correct answer is not listed among the given options.
