Which of the following number will replace the question mark(?) in the given series?

1 , 1 , 2 , 4 , 3 , 27 , 4 , 256 , 5 , ?

​Given: 1 , 1 , 2 , 4 , 3 , 27 , 4 , 256 , 5 , ?

Logic: The numbers alternate between two patterns:

​Pattern 1 (1st, 3rd, 5th, 7th, 9th terms): 1, 2, 3, 4, 5 (these are increasing by +1)

Pattern 2 (2nd, 4th, 6th, 8th terms): 1, 4, 27, 256 (these are powers of numbers)

The next term in this sequence should follow the pattern of powers.

The next term in the sequence would be 5 power of 5 that is 3125

So, the number replacing the question mark will be 3125.

Thus, Option A is the correct answer.
