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

8 :48 :: ? : 143 :: 15: 195

13

8 : 48 :: ? : 143 :: 15: 195

The logic followed here is :

Ist terrm × ( ist term - 2) = iind term

As

8 : 48

8 × (8  - 2)

= 8 × 6

= 48

And

15 : 195

15 × (15  - 2)

= 15 × 13

= 195

Similarly

? : 143

13 × (13  - 2)

= 13 × 11

= 143
