If 5 is added then how 71 came as a second number.

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.

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.

I think answer should be 60 because the logic is:

+1 + 5 - 21 + 1 + 5 -21.
