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

70, 71, 76, __, 81, 86, 70, 91, ...
this is our question, split the question as
70,71,76
--,81,86
70,91,...
for every first column 70 will be constant
then for second column 71, 71+10, 81+10
therefore 70 is the answer.

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,

@Anirudh- 3, 4, 6, 8, 12, 14, ?.. ans is 18,20,24.....
concept is simple-- its prime no. + 1
so here it is
(2+1) (3+1) (5+1) (7+!) (11+1) (13+1) ..(17+1) (19+1) (23+1)..n so on...

Why is 70 taken as a constant number here?
