Median looks same as mean.
Since you have asked ten multiples of 7, so n = 10 (even)
ten multiples of 7 are -
7, 14, 21, 28, 35, 42, 49, 56, 63, 70
Median = 1/2 (n/2)term + (n/2 + 1)term.
or, Median = 1/2 x (5th term + 6th term)
or, Median = 1/2 x (35 + 42)
or, Median = 1/2 x 77
or, Median = 38.5
Here is the answer to your question.
Hope it helps you.

first ten multiple of 7 are 7,14,21,28,35,42,49,56,63,70. Number of term are 10 that's even. Media=1/2(n/2)+(n/2+1). 1/2(10/2)+(10/2+1). 1/2(5th+6th). 1/2(32+42).1/2*77=38.5

First 10 multiples of 10 are:
7,14,21,28,35,42,47,54,63,70
No. Of observations=10(even)
hence,median=1/2(n/2th obs.+n/2+1th obs.)
=(10/2th + 10/2 + 1th obs.)÷2
Observations are already in ascending order
=5th + 6th obs.=35+42=77
=Median=77/2=38.5
Hope it helps
