A is the mean of 5,10,15,20 and 25. So
 
a= \frac{5+10+15+20+25}{5} = \frac{75}{5}=15\\ a-1=15-1=14

we need to find the median of 24, 23, 15, 14, 12 and 26.
since there are even number of observations, 

median= \frac{1}{2} \times[ (\frac{6}{2})^{th}+(\frac{6}{2}+1)^{th} ] \\ \\median= \frac{1}{2} [3rd+4th]\\ \\median=\frac{1}{2} [15+14]= \frac{29}{2} \\ \\median=14.5
