It should be 150, I suppose...

first quartile would be the mean of 75th and 76th term of ordered sequence and third quartile would be the mean of 225th and 226th term. So the terms in between them would be 150....

By the way the distance between the first and third quartiles is known as the Inter-Quartile Range (IQR).
