Answer 1

hope helps..........!!

Answer 2

x=22

11 ,13 ,15 ,19 ,x+2 ,x+4 ,30 ,35 ,39 ,46

Median = 25

n=10 (even)

Median = $\frac{(\frac{n}{2}) +(\frac{n+1}{2}) }{2}$

Median = $\frac{(\frac{10}{2}) +(\frac{10+1}{2}) }{2}$

Median = $5^{th}$ term and $6^{th}$ term

Median =$\frac{5^{th}+6^{th} }{2 }$

Median = $\frac{x+2 +x+4 }{2}$

Median = $\frac{2x +6}{2}$

25= x + 3

x=22
