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
Answer & explanation
Correct answer: option 4
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.
