The consecutive multiple of 7 in the first 50 positive integers are 7,14,21,28,35,42,49.
The median of this set is the fourth element(after arranging in ascending order),
because the set has 7 elements.

The fourth element(median) is 28(Option A)

IMO, I think this question needs to be rephrased to say the maximum number is 50.

The first 50 positive integers are 1, 2, ..., 50. So, no need to add that.

In a consecutive set [of multiples] of integers, mean = median, and

mean = first term + last term divided by 2.

7 + 49 = 56
56/2 = 28

What is the median of the consecutive multiples of 7 in the first 50 positive integers?

A. 14
B. 21
C. 28
D. 35
E. 42

We can use the following formula:

median = (first multiple in set + last multiple in set)/2

Since 7 is the first multiple in the set and 49 is the last:

median = (7 + 49)/2 = 56/2 = 28

Answer: C
