9, 13, x + 4, x + 8, x + 11, 21, 26 is 19 then x is ______

a. 10 b. 11 c 15 d. none of these​

Answer 1

Answer:

(b)11, mark me brainliest please

Step-by-step explanation:

Here number of terms are 7

which is odd

so using formula

$median = ( \frac{n + 1}{2} )th \: terms$

$19 = \frac{7 + 1}{2}th \: term$

$19 = 4th \: term$

$19 = x + 8$

$x = 19 - 8$

$x = 11$
