If m is a positive odd integer, what is the average of a certain set of m integers?
1) the ints are consecutive multiples of 3
2) the median is 33
Does the median of a set of integers indicate how many terms there are in the set? I know the median equals the average but still I could not figure out (I have not done the maths though) how many terms are in the set.. ??!!
consecutive ints

the ints are consecutive multiples of 3
This statement is insufficient, because we dont know the number of terms, we just know the set consistes of consecutive multiples of 3.
Statement II
median = 33, this statement is clearly insufficient.
Combining I & II
consecutive multiples of 3, median= 33, since the set is evenly spaced i.e. it consists of consecutive integers, therefore, mean=33
Hence C.
Hope this helps.
