52

Explanation:

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

Average=((x+5)+(x-9))/2
Average=(2x-4)/2
Average=x-2
Therefore, x-2=50
x=52
