Answer:
50 + 50 - 15 + 3
Step-by-step explanation:
Question 1:
48 + 63 + 28 + 44 + 43 = 226 minutes
41 + 40 + 15 + 1 + 39 = 136 seconds
136 seconds = 2 minutes and 16 seconds
The answer is 228 minutes and 16 seconds.
Question 2: 228 minutes = 3 hours and 48 minutes
The answer is 3 hours and 48 minutes, but if you're also counting seconds, add 16 seconds to the end of it.

Answer:
29?
Step-by-step explanation:
Since this is an arithmetic sequence, you can conclude that
the addition to the number is constant.
Let x = the number asked
k = constant
number added to the sequence
7 + k = x
x + k = 17
Solve the system of equation:
7 + k + k = 17
7 + 2k = 17
2k = 10
k = 5
Therefore, the missing number is 12 (7 + 5).
