@Harshal:
We have to find "which pair of numbers comes next (given direction)".
Given: [61] 57 50 [61] 43 36 [61] __ __ and so on.
57 - 7 = 50
50 - 7 = 43
43 - 7 = 36
36 - 7 = 29 (Required number)
29 - 7 = 22 (Required number)
22 - 7 = 15
15 - 7 = 08 ... and so on.
I hope you understand. Have a nice day!

I think Option b & d can also be correct one. Because they have difference = 7.
Then why you have chosen E as your answer?
