70 , 70 + 1 = 71 , 71 + 5 = 76 | 70,71,76 .
70 , 70 + 11 = 81 , 81 + 5 = 86 | 70,81,86.
70 , 70 + 21 = 91 , 91 + 5 =96 | 70,91,96.
70 , 70 + 11 = 81 , 81 + 5 = 86 | 70,81,86.
70 , 70 + 21 = 91 , 91 + 5 =96 | 70,91,96.

Very simple 70 is repeting after every two series, thus I hope 70 is the right answer
70, 71, 76, __, 81, 86, 70, 91,
70, 71, 76, __, 81, 86, 70, 91,

@Abhinaw.
5 is not added to 70, 5 is added to other numbers but 70 is repeating after every two numbers.

70 is const. As it keeps on just repeating. It's the logic behind. Afterall it's logical reasoning test.

+2'3 +3 +4'3 +5 +6'3
It is 2 cube and so on.

There is no logic behind why 70 has taken as constant you have to assume it by your reasoning skill.

I think the answer should be 96 then the next number will be 70 as it is constant after 2 digits.

77 is wrong ans once think. Apply your logic to all the numbers it will not work.

I think answer should be 60 because the logic is:
+1 + 5 - 21 + 1 + 5 -21.
+1 + 5 - 21 + 1 + 5 -21.
