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#
