To find the median of a series, we need to arrange the numbers in ascending order. Let's assume the series is represented by x1, x2, x3, ..., xn.
Since the median is 10, we know that there are an equal number of observations above and below 10. Let's say there are n observations below 10 and n observations above 10.
So, the series can be represented as x1, x2, ..., xn, 10, xn+1, xn+2.
Since there are 2 additional observations, the series becomes x1, x2, ..., xn, 7, 10, xn+1, xn+2.
Now, to find the median, we need to determine the middle value of the series. Since there are an odd number of observations (n+2), the middle value will be the (n+3)/2th value.
Therefore, the median of the series x1, x2, ..., xn, 7, 10, xn+1, xn+2 is the ((n+3)/2)th value.

It will be 10 only
