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

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.
