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.

Just because 70 is constant, it doesn't apply that logical answer should be 70.
Actually the question itself isn't logical.
The correct series should be 70, 71, 76, 80, 81, 86, 90, 91, 96...and so on.

the question is 70 71 76 -- 81 86 90 91.
see the difference between 70 71 & -- 81 & 90 91 the difference is 1.
If you see the 71 76 & 81 86 &91 96 the difference is 5.
If you see the 76 -- & 86 90 the difference is 4.
So this pattern follows the 1 5 4 series.
So the answer be 80. and not the 70.
