Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.

17 : 4607 :: 11 : ? :: 23 : 11615

1199

Pattern followed is :

2nd number = (1st number)³  -  [ 1st number × (1st number + 1 ) ]

We have ,

17 : 4607

2nd number = (17)³  -  [ 17 × (17 + 1 ) ]

= 4913 - 306

= 4607

&  23 : 11615

2nd number = (23)³  -  [ 23 × (23 + 1 ) ]

= 12167 - 552

= 11615

Similarly ,

11 : ?

2nd number = (11)³  -  [ 11 × (11 + 1 ) ]

= 1331 - 132

= 1199

1199 is correct answer.
