4 0

Step-by-step explanation:

Here n = 8 (even number)

\therefore \:  \frac{n}{2}  =  \frac{8}{2}  = 4 \\  \\\&\:\:   \frac{n}{2}  + 1 = 4 + 1 = 5 \\  \\ hence \:  \\ median = \frac{ {4}^{th} term +  {5}^{th} term}{2}  \\  \\  \therefore \:  49 =  \frac{x - 1 + x + 1}{2}  \\  \\  \therefore \:  49 =  \frac{2x}{2} \\  \\  \therefore \:  49 = x \\  \\  \huge \purple { \boxed{\therefore \: x = 49}}
