Answer:
2/3
Step-by-step explanation:
7/12+1/12=8/12
<u>8</u> / 4 <u>2</u>
12 / 4 3
Final answer 2/3
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).
So one trip = 4 km
two trips = 8
8 + 4 = 12
i believe your answer is 12
