Answer:
If 8, 17, x are in A.P.
=> (8+x) = 2*17
=> 8 + x = 34
=> x = 34 - 8 = 26
Therefore, x = 26

Answer:
For arithmetic progressions to work, we need to ensure that the difference between consecutive elements in the series is the same.
Therefore we know that
x - 8 = y - x = z - y = 20 - z
Since 20 - 8 = 12 and there are 4 elements apart in the series, the difference between two consecutive elements in the series should be 12/4 = 3
Therefore
x = 8+3 = 11
y = x+3 = 14
z = x+3 = 17
