52

Explanation:

Let $x$ $x$ be the number of jelly beans in the jar.
Patrick guesses $(x + 5)$ $(x+5)$ jellybeans and Brandon guesses $(x - 9)$ $(x-9)$ jellybeans. The average of their guesses is calculated by adding their guesses and dividing this total by 2.

Average $= \frac{(x + 5) + (x - 9)}{2}$ $=((x+5)+(x-9))/2$
Average $= \frac{2 x - 4}{2}$ $=(2x-4)/2$
Average $= x - 2$ $=x-2$
Therefore, $x - 2 = 50$ $x-2=50$
$x = 52$ $x=52$
