Using mean function to take average of 4 columns for every row of data

I'm just starting to get familiar with Matlab's mean function, but I'm confused as to how I can use it to get an average of multiple columns and display the result for every row of data. Details are as follows:
I have a 5000x14 matrix of data
I would like to average columns 7-10 for each row WITHOUT the use of a for loop. This should result in a 5000x1 matrix.
Some guidance would be very much appreciated.

A=rand(5000,14) % Example
a=A(:,7:10);
out=mean(a,2)
