If every team plays exactly 1 match with every other team exactly once then Total Matches \(= \frac{8*7}{2} = 28\)
i.e Total matches if every team plays 10 matches with every other team = 28*10 = 280
Total Wins = 280
For them to be in arithmetic progression of 8 terms, Mean = median \(= 280/8 = 35\)
For mean/median of 8 terms in Arithmetic progression to be 35, the terms can NOT be consecutive so they must for an Arithmetic progression of even terms with median 35
i.e. Numbers of wins will be {28, 30, 32, 34, 36, 38, 40, 42}

Total matches if every team plays other team once = 8C2 = 8*7/2 = 28
So if every team plays other team 10 times, then no of matches = 280
Now, no. of wins needs to be in arithmetic sequence and we need to find least possible largest number in this sequence, which means given a sum, we need to maximize the smallest number in the sequence.
\(S = \frac{n}{2}*(2a + (n-1)*d)\)
\(280 = \frac{8}{2}*(2a + 7d)\)
\(70 = 2a + 7d\)
\(a = \frac{70 - 7d}{2}\)
We need to maximize a, so we need to minimize d, so we will start with d = 1 and see when we get an integer value of a.
d = 1, a = 63/2 (Not possible)
d = 2, a = 28
So last term will be => a + 7d => 28 + 14 => 42
IMO: B
