List I: 3, 6, 8, 10
List II: x, 3, 6, 8, 10  Choose the correct choice from the following:	A) 7	B) 8	C) 9	D) 10	E) 11
List I has even number of terms, thus its median is the average of two middle terms (when arranged in ascending/descending order), so median=(6+8)/2=

<output>7</output>
7.   List II has odd number of terms, thus its median is the middle term (when arranged in ascending/descending order). As no other number in the list equal to 7, then x=7.   7nswer: 7.
