A1 = first term = 4
a2 = second term = a1+5 = 4+5 = 0
a3 = third term         a1 + 5 + 5 = a1 + 5(n-1), where n is the subscript that represents which term we're discussing.

an=4+5(n-1).

Is this correct?  Let's check it and find out.
What is your prediction for a2?  Here, n = 2.  Then a2 = 4+5(2-1), or 4+5, or 9.  That agrees with the given sequence rule.

Thus, the 250th term would be 4+5(250-1).  Evaluate this, please.

Answer:

The median is marked at 161cm instead of 162cm.

The right part of the box (the upper quartile) is marked at 172cm, while the interquartile range is 17cm, so the upper quartile should be at 154cm + 17cm = 171cm.
