Answer:
9:50
Step-by-step explanation:
It appears the sequence has 0:51 as the first difference, and those differences increase by 0:01 in each interval. That means ? must be chosen so that ...
? - 8:58 = 0:52 ⇒ ? = 8:58 +0:52 = 9:50
10:43 -? = 0:53 ⇒ ? = 10:43 -0:53 = 9:50
The missing time is 9:50.
