Answer:
60 minutes
Step-by-step explanation:
we can see that the number of minutes increases by 8 each day
(12 + 8 = 20, 20 + 8 = 28, 28 + 8 = 36...)
So, because we have the value for the previous day (day 6) we know that we can simply add 8
52 + 8 = 60
So, the predicted number of minutes for day 7 is 60
