Answer 1

A) 256 is correct answer

Answer 2

Hii !!

1 , 8 , 27 , 64 , 125 , .......... ?

Here,

1³ = 1 , 2³ = 8 , 3³ = 27 , 4³ = 64 , 5³ = 125.



As we can see that the series is cube of 1 , 2 , 3 , 4 , 5 .





So,



Option ( b ) is the cube of 8.


Option ( c ) is the cube of 9.


And,

Option ( d ) is the cube of 10.


Whereas , 256 is not a cube of any number.


So,

Option (a) is the correct answer.
