Answer 2

The missing number (?) is "3125".

Step-by-step explanation:

The given sequence are:

1,4,27,__,3125

1 = $1^{1}$ = 1

4 = $2^{2}$ = 2 × 2 = 4

27 = $3^{3}$ = 3 × 3 × 3 = 27

? = $4^{4}$ = 4 × 4 × 4 × 4 = 256

3125 = $5^{5}$ = 5 × 5 × 5 × 5 × 5 = 3125

Hence, the missing number (?) is "3125".
